Definitely not the Ghost. I don't like to see me scare my friends and when people watch that episode they think i have a serious problem. I don't have any problems! *stomach growls* Anyone want to lend me their body for a moment?
For me, my favorite episode is "The Kiss", between the showah of slime part and the things gumball did to try an get his mind off that awkward kiss, it was kind of interesting and fun to watch at the same time! so that's why it's y favorite!
