Sir William Wexell Wingding Whizzlebang the Third (also known as Wiggy Jiggy Jed) was Billy's dog for one episode Dream Mutt. He was originally four different dogs that were used in a game show Billy entered because he wanted a dog, Harold (his dad) wanted him to only have one but Billy wanted them all so he decided to use Grim's scythe to combine them the end result was a talking Hanna-Barbera like dog with a green hat that floated above his head, a black tie, and spoke like Yogi Bear.
