You have a door in the center hallway, allowing you to block of enemies. The power to the door goes down fast, so recharge it using the button on the monitor cameras. The door only repels Withered Mario and Yoshi. Anyone else can slip in the second the door is opened. Withered Tails will take away all of the door power if you close it on him instead of using the light. Toy Mario and Yoshi can get stunned if you use the air vent lights while they're in. Withered Sonic needs to be watched on the cameras to slow him down. If the Withereds (except Tails) get in, there's a small chance the mask will work. Rare screens and Shadows can appear. Can't wait
