I redesigned the Grapefruit Monster.
I also made small changes to the elephant. The Grapefruit Monster can now jump while he goes back and forth, which is why he's on the top in the picture even though he starts at the bottom. I also made it so the GM can change directions randomly suddenly, so you never know where he's going to go.
I had a really tough time trying to make it so the GM (I got sick of typing "grapefruit monster") doesn't get stuck inside the ledges. This usually happens when he jumps and hits the end of the ledge diagonally. But I think I made it so he won't do that any more. If you recall, I had a really tough time with the same thing with the elephant.
