One of the villages in Superbird is inside a box. The sunset is painted, and it's kinda obvious in the lightning.
Superbird: "I hath a question. There are no exits to this village. What if thou want to leave?"
Cat: "Why would we want to leave? This village has the two best things! Sunlight, and we live in a box. What else would we want?"
Supebird: "Fair enough."
