The study group puts the last touches on their diorama. When Troy's long-lost monkey Annie's Boobs emerges from the air vents and steals a paintbrush, Chang strips down and dives into the air vents after him. Chang uncovers a treasure trove of the groups' old knickknacks that Annie's Boobs has been collecting. The lost, forgotten items send the group on a trip down memory lane.
