I should be reading, but instead of course I'm on CS. Anyways, this is the flying mint bunny (from Hetalia) presumably bringing rainbows to the skies because it can. I like to imagine it's flying over Italy an he's like "GERMANY! look at the pretty rainbow, Germany! I hear there's-a gold at the end of one of those, maybe we should look! If we find it we can buy a whole lot of pasta!" Drawn from memory, so no refs. Comments & crit welcome and appreciated
