Dungeon Diaper Carroll

So, I'm halfway through "Dungeon Crawler Carl" If you've read the book, welcome, if you haven't it's basically a sci fi RPG novel and look it up.

For this post, i'm wanting to play off of it, and instead of such a scary and tough dungeon that Carl has to go through I'm wanting some suggestions that revolve around diapers and/or wet and messy.
