Treg Brown, the sound effects editor, contributed one of the characters in the cartoon; a bird with a waffle pan head.
At one point in the pan of the various denizens of Wackyland, a character with large glasses comes out of a pot and says, "Hello, Bobo." This refers to animator Robert Cannon, whose nickname was Bobo and who did wear big glasses. On the pot are the words "Treg's a Foo", refering to sound effects man Treg Brown. (Foo, incidentally, is a nonsense word from the Smokey Stover comic strip, a big influence on this cartoon in terms of humor and visual style.)
In animation historian Jerry Beck's 1994 poll of animators, film historians and directors, this cartoon was rated the eighth greatest cartoon of all time.
