Utapau

Utapau, also known as the Whiffle Planet, was full of holes. The holes were formed when bacteria consumed the lactic acid in the planet's mantle, releasing carbon dioxide gas and leaving giant holes in the crust. Every year, the local Utapauns complained vociferously to the local town council to fill in the holes, but the local government wasted all their money on bridges to nowhere and self-esteem education programs.
