 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 (I) (qv), whose  nickname was Bobo and who did wear big glasses. On the pot are the  words "Tregs a Foo", refering to sound effects man  Treg Brown (qv). (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.)
