[xu-] Professor X is in the [4] bathroom of the [-e] electricity plant where he is playing with an electric 宀 dollhouse that is next to the sink. He notices there is a glowing electric ハ fin inside it, and he uses his mental powers to lift it up. That was in fact a special switch that he triggered by moving it, causing the tile wall behind the 宀 dollhouse to open up, revealing a huge 穴 cave. Professor X wheels into the 穴 cave which is brightly lit by electric lights.
