Edgar is the bull that Peter brings to The Drunken Clam in "The Woof of Wall Street".
In an effort to keep the bull tame, Peter cinches its testicles with his belt. But after briefly being pacified by listening to Tom Cochrane's "Life is a Highway", the bull goes on a rampage and destroys the bar. Back at home, Edgar's father confronts him after reading about his rampage but he claims he was studying for his college tests. But when his father uses the word 'sanguine' and Edgar fails to recognize it, he is exposed as a liar.
Edgar joins several other animals of the show as well as the cast in singing "Blue Shadows On The Trail" in "Wild Wild West".
