H is for Haiti

 I'm Tipingee, She's Tipingee, We're Tipingee, Too

A girl lived with her stepmother. The woman collected firewood and sold her stepdaughter as a servant to the guy who carried her load. Tipingee heard their talk and formed a plan: she visited her classmates and asked them to wear dresses of the same color as the ones her stepmother would put on her. When the old man saw everybody dressed alike, he asked which girl was Tipingee. The children had an "I'm Spartacus" moment where they all claimed they were her. After three episodes of that, the old man enslaved the stepmother instead.
