Wu

Wu is one of Chang's sons, found in Dinos Downstairs.

How to Rescue
Wu is stuck inside a small heater near the start of the level. To save him, all you need to do is shoot the switch at the front of the heater (near the stairs) using Bungalow to turn the heat down. Then, enter via the small gap to save Wu.

Trivia

 * In the NTSC Dreamcast version, Wu and Juan Luis had their names switched by accident.
 * If you attempt to rescue Wu before switching off the fireplace and manage the rescue, you will get fluffed and Wu will disappear, but will not be counted as rescued.
