Jesus Christ on a pogo stick.
I really like his design. It's cute and goofy, just like his personality.
Anyway, I'm fine with Shrunk's design; It suits his character. I mean he's not cute or anything, but..I mean, it's Shrunk, I don't think he's meant to be lol.
Personally I don't think he should have been an axolotl. I mean, why would you associate an axolotl with psychology, expressions, or comedy? How many kids even know what an axolotl is?
I used to think of him as a human having a bad hair day when I saw him the first time asking for signatures. I can't unsee it until now. Axolotl looks cute in real life but he looks closer to a human to me than animal haha
