Schopenhauer is another of Oscar the Grouch's pet elephants. She appeared once in Learning About Letters, when Telly Monster showed the viewers something that began with the letter E. Telly Monster knocked on Oscar's trash can once. Oscar suddenly pops up & said, "What do you want?" Telly replied with, "Uh, I'm not here to see you, Oscar." Oscar said "Oh, good" & ducked right back down into his trash can. Telly knocked again & Oscar came up again. He said "What?!". Telly said, "Uh, I'm here to see Fluffy, Sophie, Blitzen, & Schopenhauer." Oscar said, "Well why didn't ya say so in the 1st place?" He goes back down & says, "Hey, Pachyderms Four, someone to see ya." Then, suddenly, 4 elephant trunks come up. Telly holds a sign with the letter E on it. He said, "E. As in elephants."
