This one was amusing to read. I'm not sure how to rate it, so I'm giving it a 4/5 because it was a humorous read. But really it should be 3/5, because the story defies logic quite a few times...
What's not to like?
The constant 90s pop culture reference?
Ax's love for commercials, and his acting dramatic like the closing scenes in a soap opera before commercial break?
Marco saying "We can go as burgers ... or boogers", meaning they can go in as either cows or flies. HA.
SPOILERS
There isn't really any forward story momentum here. It's just an amusing and entertaining filler book. I liked it. It was a silly read. Lots of lame jokes, cheesy reference, and just silliness.
This book, while not a forward plot progression, gives me hope that there are still more good books to come in this excellent series. I may be 32 years old, but these are still fun reads.
Growing up is for boring people. Fun people never grow up, they just "grow wiser" and more knowledgeable. With that sentiment, I recommend reading this series... especially if you remember the 90s. Ahh, the flashbacks. The days of tube tvs and ancient computers. The days when I actually played outside as a kid. The days when my parents would tell me it's sunny out, go out and play somewhere, and I'd just wander away all day, them not knowing where I was, nor caring, nor worrying. Then me coming home and watching my 3 television channels on an old black and white tube TV my grandfather got out of the garbage pickup. I would watch the fuzzy channels... hockey (typical Canadian child), or Tin Tin in french (because there weren't many options... not that I actually understood french). Ahh, the 90s...
BUT I DIGRESS
In this book the story is pretty basic. Eric of the Chee, the androids the pemalites created, show up disguised as a FedEx truck... yup... dog droids dressed up as a van.... hilarious.
We find out there is a meat packing plant and a animal testing lab that the Yeerks have bought recently.
Basically it turns out Visser Three was trying to remove human free will. It didn't work of course, but in the end the Animorphs break in and save some chimps, and later some humans.
There was a ridiculous scene wherein the animorphs get on top of a truck, and break into the back of it to figure out what kind of animal the Yeerks are using (whether it's a chimp or something else)... the plan was that they would morph those animals, and release the real ones.
They did this, and it what positively bizarre and amusing. One guy in a car actually seemed to be cheering them on as they broke into the back of the truck.
They caused a car accident too. Fun.
Then we have the hilarious scenes with Marco driving a truck... again... and going on two wheels... and the human controller guards criticizing his driving...
All is all a very fun book to read. This one probably made me smile, and burst out with "HA!!", in reaction to funny scenes, more than most other books. That's a plus in my opinion. Way to go Ghost Writer.
