Found deep in a closet of childhood things, so I reread it. How can a children's book that introduced elementary school children to the words "inexorably" and "lagan" boldly declare that turtles can breathe underwater and then structure half of the plot around that statement? Also, Donatello says "dammit". I rediscovered my childhood shock at seeing that word on the page. What a strange 90s turd of a book.
When I was 7, this was the best book ever. The TMNT were my favourite people in the world, right after Robocop and MacGyver, and twenty years later I'm still bummed my mom never bought me the rest of this collection.
