Hospital Days -- breakthrough

This was drawn for a rp with my friend. The story goes that Zim had gotten sick from a disease that Dib injected into him. After being cured of it, he found he cant walk cause laying there being restricted from cables connected to his arm has messed up his leg muscles. He had the thought of using the legs in his PAK and now will use them as a guide, which will help much more then he thinks. The background is the hospital hes in, no its not the normal kind, but his friends.... the machine has random stuff cause I had no idea what to really put there. and heres a quote from the rp

"I'm not gonna be a whiny human about this, that's stupid. I'm Irken, I was hatched and trained to be strong" -Zim
