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.
His appearance is almost identical to Snuffy but with a a slightly rounder head, longer fur, and smaller eyes.
Schnuffleupanegger is a clear 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 famous film series, The Terminator.
