Update: 17 March 2017

I've been meaning to update this for months. Original review has been deleted / changed from 1 to 5 stars / I'm an a-hole, etc.

I took major issue with my (then) 6 year-old bringing the Captain Underpants books home from the school library. I couldn't understand why any public school would even have these books: the main characters are disrespectful little sh*ts who mock their teachers and classmates and get in trouble all the time. Oh, and half the words in the book being purposely misspelled made me want to smash something.

I may have said something in my original review about this being the kind of book that turns kids stupid.

Well, whatever.

I took my kid to a Dav Pilkey book signing, and, well, fine, I admit it, I was wrong. Pilkey himself was a complete class act, a total natural with the kids. He quizzed them on elements of the novels and gave out hand drawn posters to the winners. He also prepared an animated slideshow telling the story of his novel being rejected by publishers hundreds of times until someone finally accepted it -- it was a really sweet lesson of persevence for the kids. I also liked that he talked openly about having ADHD, and explaining that while the condition made him a sucky student, it also made him a great comic book author, which led him to creating Captain Underpants. He also said that he based the two main characters on himself as a gradeschooler, and like the characters in his books, he wasn't bad at all, but bored by traditional school and labeled an underachiever because of his ADHD. All of this is important stuff for kids today to hear. Oh, and Pilkey should be credited for covering these heavy topics in a way that kept the kids engaged, laughing, and happy.

My kid and I somehow ended up ass-last in the book signing line, and an hour later when it was *finally* my kid's turn, Pilkey treated my son as if he were the first kid he'd seen all day. The guy talked to my 7 year old about writing books, answered his questions about the novels, and signed and drew a personalized picture in every single novel in the stack we'd brought to the table.

Sigh. Like I said, I'm an a-hole.

These books won't turn your kid stupid.

Children recognize and laugh at the misspelled words, and correct them as they read. The main characters do and say things that young readers recognize as over the top or inappropriate, and they scold the characters as they crack up laughing.

Anyway, the books are harmless, they bring a lot of joy to kids, and the author seems like a really nice person.

Disregard my original review.

And if you're reading, Dav, sorry about that.

Okay guys....this is the seventh book in this series and the conclusion to Booger Boy. I have to say the only thing I really enjoyed out of this book was the Squishies lol. I have never done that and really want to in the future. Maybe on a day where I'm already going to be cleaning the bathroom teehee.

Overall the first one was better. I did like that George and Harold got two new pets. They are cute. What happens at the end was a nice transition for the next book. They should have waited 2 whole days for the cooldown!

I don’t know how many books of this series I’ve read with my kids, nor how many times I’ve read each one. I believe it all started when I was teaching 1st and 2nd grades in Texas around 2000-2002. My students loved Captain Underpants and the stories got many reluctant readers to happily pick up a book. I later bought the series for my two first born kiddos (who are now 14 and 16 year olds) when they were much younger and our beat up copies have made the rounds, over the years. The books contain lots of toilet humor, but overall they are quite clever and include some high-level vocabulary for young readers. This month I’ve been reading these aloud with my 9-year-old and we’ve both laughed quite a bit!!

I read this to my five year old daughter in two sittings. One short one and one long one. She loved it. I did do some mild censoring, mainly replacing the word "stupid" with silly. I cut out one "shut up." And started censoring "nerd" in the beginning of the book but by the end I gave up. Basically, I was trying to skip words and phrases I didn't want her to use. If she were around 8, I probably wouldn't have been as strict.

This is the second chapter book I've read to my daughter. The borderline potty humor and over the top silliness really did a good job of holding her attention. Personally, I couldn't follow what was going on, some of the phrasing was awkward to read aloud, and I was bothered by the lack of women characters but overall this was a positive reading experience for my five year old.

The more this series goes on, the more ridiculous it gets and I love it.
We have time travel, we have robot booger bad guys, we have a Freaky Friday thing where two characters switch bodies, we have all kinds of meta, and more breaking the fourth wall.

Meh. This series is losing its charm. George and Harold are still making fun of Melvin, though in their defense Melvin did turn into a more traditional villain than just a sad kid. However, I still don’t like that they call him a lame nerd, as if being smart and liking to learn is a bad thing. And though Melvin was an annoying smarty pants, I don’t like the nerd teasing—hits too close to home 😆

The other thing that spoiled this book is the time traveling. Can we please not go there? The plot hoops that had to be taken to make the storyline work were ridiculous and outlandish and lost the tongue in cheek charm of the early books. It felt like the author was trying to outdo himself when he really didn’t need to. Sometimes more is just more.

Captain Underpants and the big bad battle of the bionic booger boy by Dav Pilkey was a funny and a weird book. The main characters are George, Harold, Melvin, and don't forget Captain Underpants. My favorite character is Captain Underpants but when you read the book it's weird but you can figure it out when you read it. I think this book will make you laugh but when you get into it it gets weird. My favorite part is when Harold and george make a comic book about Melvin and they make him look silly. This is a book I will recommend to many people

Point of view 8 year old boy: Side split tingly hilarious.

Point of view parent: kept 8 year old boy busy and entertained (thus worth it's weight in gold). It took him a few days to read this, but as it was so funny he kept at it until he had finished. He even read some bits aloud to share with the rest of us because they were so good.

This is one of those series that you had started reading, but stopped reading after a long while. Now, finally trying to catch up. Another okay but has its moments I guess, type of read.

It’s not Banned Books Week till September, but one of the Library Reading Challenges for this year is to read a banned book. Since Captain Underpants is sort of a personal hero, I figured, what better way to fulfill this challenge? Uh-oh, I read Book 6 way back in 2016! And this (Book 7) is the sequel! Well, just had to go back and reread Book 6, which if you remember is, “Captain Underpants and the Big Bad Battle of the Bionic Booger boy, Part I: The Night of the Nasty Nostril Nuggets.” Luckily for you, I posted a review, so’s you won’t have to go though the toil of reading it (though I do so recommend it). In brief, Melvin Sneedly, nerd extraordinaire (I do identify), has accidentally developed a machine that, he hoped, would fuse himself with a robot, but sneezed at the last minute, making the whole thing a giant booger monster. With the help of Captain Underpants, a bionic hamster (don’t ask) and, of all thing’s, Melvin’s parents, the booger monster was defeated by reversing the Combin-o-thingy, but uh-oh, it seems Melvin’s and Mr. Krupp’s brains were interchanged, setting the stage for the next thrilling adventure!

So in Book 7, our intrepid heroes consult with Melvin, who has managed to create a time machine as well as a memory eraser (a direct plagiarism from “Men in Black,” no doubt) and a mockup of the Combin-o-thingy. He tells Harold and George that they can go back in time and surreptitiously get the original Combin-o-thingy from Melvin’s parents, as well as erase their memories of the whole thing, and bring it back and reverse it all. Well, of course, the time machine malfunctions, resulting in the boys obtaining a pet dinosaur, before returning. In the meantime, the booger monsters have been blown into space, but they hitch a ride on a returning spacecraft and wreak havoc on…Confused yet? And there are the usual hilarious cartoons about Mr. Krupp and Captain underpants, as well as of Melvin, the Flip-O-Rama animation, and reference not only to previous books (specifically “The Attack of the Talking Toilets”) as well as to previous pages in the current book.

I continually enjoy and have belly laughs at this series, and look forward to the next one every year. Four stars (five if I were 11 again).

Es war klar, dass es eine Fortsetzung geben wird. Und hier ist sie. Sie trägt zwar den Untertitel „Die Rückkehr der rüpelhaften Rotz-Roboter“, aber sie spielen nur eine untergeordnete Rolle. Vielmehr lässt Pilkey im siebten Band seiner Captain-Underpants-Reihe seiner Fantasy freien Lauf. Und die kann bekanntlich sehr abgedreht sein.

Wieder vereint der Autor sehr viele Ideen zu einer abstrusen und vollkommen sinnbefreiten Geschichte, was quasi das Markenzeichen dieser Comics ist. Und genau deshalb so gut ankommt. Nonsens hat immer schon eine Faszination auf uns Leser ausgeübt. Eine zusammenhängende Geschichte lässt sich nicht erkennen. Vielmehr ist es eine Aneinanderreihung diverser Ideen, die aus dem Kopf des Autors gesprungen sind.

Aufbau und Erzählweise des Comics sind in gewohnter Manier umgesetzt worden. Wieder gibt es den Comic in Comic und wieder gibt es die Fliop-o-Rama, die aber meiner Meinung nach etwas künstlich eingebaut wurden. Ganz so, als wüsste Pilkey nicht, wie er sie sonst einbauen sollte oder als ob er sie vergessen und nachträglich eingezeichnet hätte.

Allerdings zählt meine Meinung nur bedingt, denn ich persönlich bin von der kompletten Reihe nicht sonderlich angetan. Ganz im Gegensatz zu meinen Kindern, die auch diesen Band verschlungen und sich sehr dran erfreut haben. Nach ihrer Meinung ist der Dog Man zwar witziger, aber Captain Underpants kommt sehr dicht dahinter. Ich überlasse es also wieder meinen Kindern, dieses Buch zu bewerten.

Fazit

Die abgedrehte Geschichte ist wieder gut bei meinen Kindern angekommen. Es sind sehr viele Ideen enthalten, die Pilkey umsetzt, die aber nur mit sehr viel gutem Willen sowas wie eine Geschichte ergeben. Bei der Bewertung des Buchs schiebe ich meine Meinung in den Hintergrund (für mich ist sie zu abgedreht) und überlasse das Feld meinen Kindern, die diesem Nonsens sehr positiv gegenüberstehen.

So, this was the sequel to the last book. We left off with the three snot-robots terrorizing everyone. In steps Sulu, the mutant gerbil, who gobbles them up and spits them out to Uranus (joke intended).

All is fine and dandy.

Then we learn that Captain Underpants and Melvin have had their brains swapped. That causes much hilarity. I would have preferred if Pilkey had not renamed the characters at this point, but I suppose it might help younger readers.

So, Melvin built a time machine, since that was easier to do than a separator. The boys traveled back in time to get the pre-smashed combinator. The boys also had to write a comic book where Melvin was the hero and cast in good light. They did the opposite, which infuriated Melvin. So, the boys bring back the combinator and Captain Underpants and Melvin are back the way they should be.

Meanwhile, a space crew went to explore Uranus. When they approached, the saw robots and toilets on the surface. Their spaceship was slimed with the alien robot boogers. The decided to return to Earth. Of course, they brought the aliens back with them.

Melvin had set his machine that when he and Captain Underpants switched back, Melvin ended up with all the super powers. But Captain Underpants being a true superhero, took on the boogers without his powers.

The boys, for their part, traveled back in time and got a pterodactyl so they could catch up with Melvin. They reset the machine, took the powers away from him, returned them to Captain Underpants, and the boogers were defeated. All is right with the world . . . save the pterodactyl was never returned. Uh, oh!

The thrilling, and suspending seventh book in the series had me jump up, and hope that the three heroes George, Harold, and Captain would survive! The story had the team of three come across the most disgusting enemies ever. They had to fight them because of a kid named Melvin had made a mistake, and created these three monstrosities for George, Harold, and Captain Underpants. However, Melvin took Captain Underpants's powers. Captain Underpants was now powerless. Melvin was trying to be the super hero now, but he made everyone hate him. The three evil, disgusting, and ridiculous booger robots had come back to attack an airport that so many innocent people were in. George, Harold, and Captain Underpants tried to save the people, but they couldn't do it without Captain Underpants's powers. Melvin didn't want to save the people because he was once again being a jerk. George, Harold, and Captain Underpants we're on there own. But, they didn't give up. With there team work they thought of an idea, and with there perseverance they defeated the three enemies, and saved all the people at the airport!

Real Rating: 4.5

This book picks up where the last book has left off at.

Captain Underpants sends the robo-boogers into space and everyone thinks it's over, right? Wrong. Melvin manages to have his brain changed with Mr. Krupps and decides that he wants Captain Underpant's power. So he sends back Harold and George into time. The two boys visit the past and then the way past.

I don't want to give too much away with this book because there is a lot of things going on but you will come to appreciate the fact Melvin gets his in the end.

I have come to really love this series and to actually think that it was the upcoming movie that pushed me in the direction of reading these books. There is toilet humor and much misspellings but don't let that deter you or your child from reading these books. Remember these books are being told from Harold and George's views (in a way or another).

So pick up these books and read them with your child. You will not regret it!

Trailer: This book is about two young children that have to deal with their principal that they hypnotized. He now has super powers and they have to work together to solve the problems that they face in the book. One problem is how they have to go back in time just to get a tool but they can’t be seen by those people. Another is how at the end of the book they have to travel back in time to return a pterodactyl into the Cerazic period.

Review: Overall this book is really good. It was funny, interesting, and action packed. I would definitely recommend for younger people or people who just want to read something funny or stupid. This book also had a lot of details to pay attention to and characters that you would need to know. This book was easy to read but it was also confusing because of the made up words and phrases, such as Forgettchmacallit 200.

What can defeat space shuttle destroying robotic mucus? A silly dance from Captain Underpants? The power of all that is pre-shrunk and cottony soft? Or could it be a squishy of vitamin C? Never mind all that. The real questions are 1) how did George and Harold end up with a pet pterodactyl, 2) how to unscramble the brains of Melvin Sneedley and Mr. Krupp, 3) and worst of all, what happens when you use an overheated Purple Potty time machine two days in a row? According to noted fourth grade author George Beard, the answer to number 3) is “It all sounds like a setup for the sequel to a really lame children’s book!”

"I thought it was good because Trixie got shoes stolen in his mouth and oranges in his mouth and melted to the ground. In the book there was a guy who punched the thing. George an Harold made threw the stuff and Captain Underpants threw the oranges and they threw the shoes. So Harold and George went on the bottom and George went on the top and they put on the librarians coat and the dad was so surprised and it wasn't even Melvin Sneedly. Melvin Sneedly had Captain Underpants' brain and Mr. Krupp had Melvin Sneedly's brain; it's so funny."

More silly fun with George, Harold, robotic boogers, absurdly named inventions and a pterodactyl.

Once again, the end is a set-up for the next book so Pilkey is clearly in "series mode" at this point. (The actual plot for this book resolves in the second or third last chapter, so it's not another cliff-hanger per se. Just an extra chapter linking this book to the next.)

Reading the series to my five year old. The seven year old reads them himself and claims Dav Pilkey as his favourite author.

Captain Underpants and the Big, Bad Battle of the Bionic Booger Boy Part 2 is a hilarious, action packed continuation of the series. George and Harold face off against the gross villain, Bionic Booger Boy, in a wild, fast paced adventure full of absurd humor and zany battles. Dav Pilkey’s playful tone and vibrant illustrations make the story even more entertaining. While the plot is nonsensical, it celebrates imagination, friendship, and creativity. A fun, laugh out loud read for fans of the series's

Did not like how it ended on a cliffhanger. The cliff hanger could easily have been a soft cliffhanger. Instead of Harold and George trying to return, you know who they could have left it to tomorrow and the next book could have started with that tomorrow.

A hard cliffhanger like this eliminates any ability to wait for the next book. The next book wasn't titled part 3 . I didn't know I'd need to buy it to get the full story.

This feels more like selling the next book rather than actually trying to tell a story in this one.
