S2E13 Going Coconuts

Jeff cautions Wally against saying the word "coconut" while he's house-sitting. Bobgoblin, eavesdropping on their conversation, schemes to get Wally to say it. His plan falls flat, but in a twist, Bobgoblin accidentally utters the word himself. This leads to a chaotic moment as a flurry of coconuts erupts from the closet, bouncing all over the place.
