Arnold Schnuffleupanegger is a Snuffleupagus who appeared on Sesame Street in 1993, to give Mr. Snuffleupagus and some kids an exercising lesson. He speaks with a heavy Austrian accent. While his lessons primarily involve moving the snuffle, Schnuffleupanegger says that hands, arms, or whatever you have can also be used for the exercises.
Schnuffleupanegger is a reference to the actor, weightlifter and Governor of California, Arnold Schwarzenegger. As Schnuffleupanegger leaves for his next class, he tells his pupils, "I'll be back. Hasta la vista, baby!", a reference to Schwarzenegger's most famous film, The Terminator.
