This turned out so differently than what was originally in my head. At first I was going to doodle a bunch of mice with different hats and have it be funny that one was wearing an extra-large hat, but it struck me as not funny enough. Instead of abandoning the concept, I decided that the only scenario where mice would be wearing varying hats would be a party. Then I drew a cheese head, because I thought that Toph would get a kick out of it.
