Hearing that they'll receive volunteer points, Gray and Green recommend decorating the hallway to the princesses.

Meanwhile, Black Diamond creates a new Black Curse, her most powerful subordinate, Dark. After obtaining Green's Bubble Gem, Dark lifts Blue Dot School into the sky and turns it into a maze. The school, already complicated by the red carpet and exercise equipment in the hallway, becomes even more confusing, and Indigo, who had been suspicious of Gray from the beginning, confronts Gray.
