SpongeBabe (Pixiv Fanbox)

This is an idea I've had clanking around in muh brain for several years now. SpongeBabe was actually created by a (non-ABDL) artist called NeoSlashott on DeviantArt, who I've been a fan of since I was in high school. And the ol' brain has just been so full of ideas to riff on, I had to finally get some of them out of there before my head exploded.
