I know a wee piggy

A fun day at the fair becomes color chaos when one boy’s energetic pig gets loose. Upside down, piggy wallows in brown, but that’s only the beginning of this cumulative, rhyming text. Soon, he’s adding a rinse of red (tomatoes), a wash of white (milk), a pinch of pink (cotton candy), and many more. Can piggy be caught before he turns the whole fair upside down?
