Neptune's Kingdom

Willy Dooit, Applesauce and Gee-Whizzer travel to the bottom of the sea to visit King Neptune. Gee-Whizzer puts a Whammy on Willy so he can breath under water. Willy finds Neptune's throne room. No-one is there so he sits on the king's throne and that breaks the whammy. Willy can no longer breath. To save Willy, Neptune turns him into a Tunafish.
