With baked goods and coin as his new life goals, he turns to the competitive business of trading the random junk adventurer's loot every day.

This is a weird LitRPG featuring a crab who gains a system interface and decides to be a merchant. And it delivers that I will admit. But also a bunch of contrivance and people doing things for no reason at all. Like, a couple obviously evil types drop by and not only deal fairly with the merchant crab but outright generously. As opposed to, you know, killing the crab and taking what they wanted. And the baker who comes all the way out of the city to give the crab free pie? That makes no kind of sense.

So what I'm saying is that this is a lighthearted story with some odd conceits and a dash of quirks that if it connects will probably be charming, endearing, and possibly funny. It missed with me, I'm afraid.

If you want a bit of whacky good-natured fun, give this a shot. But it didn't engage me. I'm going to give it a second star because it is creative and there's some fun bits that I think will do well with the right audience. So it doesn't get in its own way, is what I'm saying. For me, though, I'll be moving on.

A curmudgeon crab gains sentience. Becomes a merchant to the multitude of adventurers in the area. Befriends a baker, develops a love for sweets. Yeah, ok, that's unique and has my interest.

But, dang, did this need to be just under 700pgs? Not at all. This needed to be 450pgs tops. It just dragged a few times.

Great side characters. Fun plot points (and some that should have been cut). There's a whole under-arcing story that amps up a lot at the end and is seeming to be a focal point of book 2.

Did this do enough for me to read book 2? I just don't know.

The power of Pie

There are very few books that I have laugh at then this one. The crab reminded me of the stereotype of an old grumpy man wanting kids to stay off his land. I loved that even though he was annoyed at first when adventurers came along, but eventually he got used to them. I loved his friendship with the baker, and his rivalry with the bully of a merchant. I am excited to see where the story goes from here.

My second foray into the LitRPG's! I stumbled upon this title during an Audible sale and thought it sounded fun: A crab gains the ability to "level up" like the adventurers around him and decides to become a merchant, selling the junk they leave by his pond for more valuable things...like pie! The bit of narration in the preview also sounded good, and with a food-related r/Fanatsy prompt for 2026's bingo, it felt like the perfect time to pick this up!

I didn't realize this until I started but...this book is REALLY long; At almost 700 pages and 25+ hours, this deceivingly charming book is the same length as other high fantasy books I've read. Luckily, I enjoyed my time and it didn't bother me, but if you don't vibe with the book it's safe to say you should just DNF to save your time. Merchant Crab felt like a combination of LitRPG and cozy/slice of life; There's very little on action-side, and we instead see our cantankerous crab slowly learn about the world beyond his pond, building up his connections, his store, facing rivals and making friends.

Johnathan McClain's narration gives so much entertainment and energy to this book! His voice for Balthazar the crab reminded me of Zeke from Bob's Burgers, fully of crabbiness but with a good heart under his shell. He gives different voices to all the different characters throughout, and I was amazed at how good and distinct they all were! The only voice I had issues with was Madeline's sometimes (sorry!). I think he easily made this book so much fun for me, elevating this to a 4⭐ experience from a 3⭐book.

The story itself is pretty simple and slow, which isn't a bad thing per say; It feels like one of those online books where the author posts a new chapter every week and it slowly builds into a giant tale. We do get glimpses into a greater narrative about the world, and by the end we have a fantastic and exciting setup for book two! Balthazar, now without his leveling system and upgrades, will adventure out with his friends to attempt to rescue Madeline from the dragon, find the witch who cursed Henrietta, fix Bouldy's broken golem core and more; He also has his side mission of meeting with the mysterious Ruby and friends who know more about the world, and a way to regain his ability to level up after having it taken away from him. I wasn't sure if this would be something I'd want to continue, but I'm excited for what comes next!

[Elizabeth Fowler]

This is a laid back LitRPG with hilarious characters that centers on a cantankerous crab that gains access to the system and decides to start trading for access to delicious pastries. I absolutely loved the world building in this. Balthazar's entire life revolves around this tiny pond but so much happens as people bring in fresh items and information. As his skills evolve so do his problems.

[Benjamin]

I really like this one. the concept is novel and the writing pulls you in. however I'm not sure if it was my mood surrounding reading it, or if I just wasn't vibing with it. I like the book but that's it, I had trouble getting through it to the bitter end.

[Dave Stone]

Great! but not without it's issues
LitRPG / Nonhuman MC / NPC to hero / light comedy (Great Audiobook)

This book is H-U-G-E!!! 698 pages, 25 hours on audio
For a lot of this book there seems to be NO progress, and the one main joke wears thin. The author HOst is from RoyalRoad and was working out how to write as they went along. They did an Amazing Job! but it's inconsistent, and there are some mistakes along the way. The biggest problem is that the author skirts the line of humorously grumpy MC and sometimes the crab is just an A-hole.
This can be hard to take when it feels like things are dragging along and not getting anywhere.
-It gets better
By the end it's pretty damn good. I immediately went for book two only to learn it's due to be released in 2 days. (what a coincidence on the timing)
So yeah I think it's worth it. If you like the book right away, stick with it through the rough parts. If book two sucks I'll come back here and change this.

The is a review of the Royal Road edition, which may have been edited before being released on Kindle.

This is a fun, and very light, progression litRPG fantasy, with strong cozy fantasy vibes. It could fairly easily be edited up to a three-star rating, and even at two stars, it's a light enough read that it may be worth reading, if you want fun and fast. It is somewhat repetitive, silly, and the character development is intentionally rather heavy handed. The world is a parody fantasy setting, with the world building built entirely on DND vibes. I enjoyed large parts of it, but also skimmed over fair chunks, as the content of paragraphs and even long passages was sometimes so predictable that it simply wasn't necessary to read them in detail.

Minor spoilers: the overall arc is very much a set-up for the next book, with success slowly building to a peak only to end in a series of epic disasters that will surely be solved in the next book... which is fine, I guess, but again, rather heavy-handed.

fun

Balthazar just wanted a quiet life in his pond. Then an adventurer stepped on him and things happened. He retrieved a scroll from the adventurer that made him an Adventurer. Still all he wanted was to sun himself on his pond, that is until an adventurer traded him pie for a sword. This a love of sweets and the drive for more was born. He starts finagling deals and becomes a merchant trading left and right all for shiny coins and sweet treats. He takes on the local merchants guild, the tax man, and misunderstandings to reap a profit. He learns that family and friends mean a lot to him. Eventually his status as an adventurer is taken away and so is a friend. So he plans to leave his pond and go get his friend back!

A funny and lighthearted story. The grumpy character learns that he was always a softy. The narrator is wonderful. The pacing is steady and the world is fascinating. Please enjoy

[Chip]

This was... fine. I think it was recommended to me as being hilarious so perhaps my expectations were too high but the humour didn't land with me even once. There were some aspects like the crab being grumpy which I felt were shoehorned in very awkwardly after the author realised "crabby" could be used for puns. Some of it felt a bit generic but I did appreciate the story setting never leaving the original location which was quite unique in the genre. I did some on ebook and some audiobook and didn't think the narrator was very good especially with women's voices. The ending was really really good though, I felt the last few chapters really picked up and almost make me want to read book 2. Not one I'd recommend overall though.

[Shelby]

This was fun at first, I liked the main character,, but about 1/2 way through it began to wear out its welcome becasue the crab kept "learning" the same lesson every couple chapters. Crab would do something that was too crabby, there is a single consequence, he'd realize he has to value other people, and everything would reset. The ending chapters were a slog to get through, as were the six different pieces of the epilogue.

[Mathew Benham]

A 25hr audio book. Im giving 6 of 10. There was no main story until halfway (No spoilers). Next, the MC himself is not only crabby but through the whole story keeps repeating the same I hate ppl/ I like ppl attitude, last issue why was this so long? 25hrs / 30 min mini adventures is just 50 short stories, I kept feeling like I got nowhere relevant after 2hrs of listening. Overall, I did enjoy this book but not that much.

[Leish]

The narration took me a bit to get used to but once I did it was really enjoyable.
It had me laughing out loud which always a big win in my books.
It was different enough to other litRPG books to keep it fresh and exciting.
I loved the characters and I’m really excited to see what happens in the next one. I’d love more of Tweedle because he’s so erratic and weird.
Highly recommend listening on audible

[Bryan]

A fun story about a crab that discovers a scroll which connects him to the "system" which allows him to gain levels, increase his stats, and gain skills. A normal pond crab ends up becoming a merchant and making friends along the way.

There are sections where this has a nice, low-stress slice of life vibe, and others with some lite action. Overall I think I enjoyed this book but it feels about 40% too long.

[Cape Rust]

Unusually Comfortable

How could you pass up a book called Merchant crab？I enjoyed the fresh concept. it was a well written book and the characters were interesting. This is another great addition to the lit RPG genre. a lot of the plot points were telegraphed and that's okay. I look forward to the next installment.

A nice slice of life from the point of veiw of
A crusty crustaceans with a salty attatude

I listened on audible aswell the voices of the characters was very fun

[Danny Moody]

Surprisingly good. Comedic LitRPGs can be hot or miss for me but this was a hit. The cast of oddball characters were really fun and entertaining. There was an overriding plot which propels the story into the next book. I’ll definitely continue.

[Craig Williams]

I had high hopes for this one but it was just ok. A little slow for my liking maybe just setting things up for book 2.. I might read the next book but its probably not one I will be jumping on as soon as it comes out.

[Paul Hefka]

A great story.

I really loved reading this book. It was funny and engaging. The story and characters were incredibly interesting and entertaining. I'm looking forward to seeing what happens next. This book is definitely worth checking out.

[Johnny]

I read this 1 well it was being posted on royal road. So needless to say I read it quite a while ago. Good story rather light hearted The crab's personality is well except from a crab.
This is a pretty light-hearted read. I do remember there is some violence but not a much.


7/10

[Wendy]

It meandered too much for me to really love it. It tries a little too hard a little too often to truly win me over. At the same time, I like how it committed to its whimsical premise, and was enough good fun that I bumped my rating up a star from an “okay” 2 to a “good” 3.

[Mark]

Semi-cozy litRPG that uses the non-standard merchant crab protagonist to point out a lot of litRPG tropes that don't make a lot of sense. However my gut feeling is that it said what it wanted to say and should have ended with this volume.

[Jeroen]

I listened to the audio book.
The narrator is excellent, his voices are hilarious.
The book itself is overly long, but enjoyable comfort reading.
The crabby crab and its companions are funny.
Were it not for the good narration, this would've been a DNF.

[Micheal]

Awesome book, interesting concepts. characters are a bit ridiculous and not much progression. The ending was so boring I accidentally forgot to finish it till I started book 2 and noticed I still had 40 mins left. Listened at 1.75x speed .

[Reck]

I picked this book up on a whim... it's fantastic. I had more snort-laugh moments on this book than I have in a while. If you ever wanted a book where the grumpy animal companion is the main character and doesn't bother picking a companion... this is the book for you.

[Nikhil Narayanan]

Litrpg mechanics plus NPC crab the result absolute chaos, adventure and comedy. Definitely takes a small amount of time to get used to non human perspective but is enjoyable read with slice of life elements mixed in

[Dylan]

The writing is poor, the lessons are ham-handed, but the idea is novel and I'm still going to read the next book in the series.

[Akshay]

BEST BOOK EVER!!!

DNF

[Mistress OP]

Hmm, I feel like this could have been something. But I found myself just turn off.
