Hi there! I am new here and just got my first Pacman, yesterday. My boyfriend and I noticed that he has a hard lump on his back, he also looks kind of awkward, nowhere near as nice as some of the frogs I have seen on here. I had him in a little container for his (purified water) bath and then that container inside a large Rubbermaid container in the case that he jumped out, and he did. I wouldn't have put him on the slippery surface myself, but I jumped at the chance and took some pictures.

I also used a water dropper to rinse away some of the dirt that is stuck on him, but he is quite dirty and it didn't work very well.
