Great Cubes of Fire! (Japanese: 四角い花火)

Pecola has volunteered to be part of a dance troupe that is to perform at a festival in Cube Town, but he has procrastinated in his practicing and finds himself unprepared and unrehearsed... and the dance is tonight! Instead of working hard, like his friend Dr. Chu who is under pressure to design new fireworks for the festival, Pecola tries to find an easy way out with near disastrous results.
