A while back, someone posted a custom porcupuffer model to replace the spike bass, but it kind of just looked like a half-eaten gumball with a face. So, I decided to get my own model:

It's a little bright but pretty good otherwise. To use it, open the rom file browser and replace root/enemy/togepuku.nsbmd

Your free to use it in your hack, but please give me credit.
