The quickest way to describe Mitsuboshi Colours might be "three little Yotsubas terrorize a local park". That description demands you read Yotsuba, which every single human being should do, but it otherwise covers everything. The show focuses on three young girls who've taken it upon themselves to be the guardians of their town, tackling such challenges as a thieving cat, mysterious locked safes, an excessive amount of bananas, and the possibility of poop. Poop is always a possibility.
