Prince

Origin
Prince is a dog who lives in the Land of Mo. Since there are no other dogs, he is a bit of a curiosity. Like all animals in Mo, he can talk, and he is playful and quick-witted, a bit of a wag.

One day the dog saved the Valley of Mo from destruction by tripping the Cast-Iron Man sent by King Scowleyow. At the dog's suggestion, the mechanical giant was turned around and sent back to Scowleyow's kingdom.
