Calvin was a clown IF but he's kind of on and off with it now. He can generate balloons of all kinds, like animals and objects, and can teleport a clown suit on at will. He is short-tempered, bratty, a bit grumpy, but is kind on the inside and can be nice sometimes. He's smart, but usually is annoyed about it. He glows when he's happy or feeling connected with someone. If an IF has a problem, they usually go to him. He also is frenemies with Cosmo, hating Cosmo yet still being friends with him.
