Wolfgang the Seal
From Muppet Wiki
Wolfgang the Seal is an excitable seal on Sesame Street, who communicates through a series of barks.
Wolfgang has a great affinity for fish. If he so much as hears the word "fish," he is apt to go into a frenzy, so other characters avoid saying the word in his presence.
He has appeared on Sesame Street since Season 22. In his early years he was owned by Uncle Wally, who taught the seal how to play a series of horns with his nose.
He also appeared in the special Sesame Street Stays Up Late!, where he balanced a beach ball (representing Times Square's annual New Year's Eve custom of lowering a large crystalline ball on top of a building) on his nose.
His birthday is December 23rd.
