Rumpel is a green Grouch (originally "Griesgram" in German, lately "Grautsch") with big energetic eyes. He lives in a rain barrel with his caterpillar Gustav. Like all other Grouches, Rumpel hates rain when others love it, but he loves rain when others complain about it.
Rumpel was added to Sesamstrasse in 1989 to replace negative characters such as Uli von Bödefeld & Oscar the Grouch: quite a few critics weren't fond of the American Sesame Street set. German kids didn't grow up in a suburb full of trash cans. After a few years of absence, the insert scenes of Oscar returned.
Rumpel, along with other international Sesame Street characters, appeared on the cover of Sesame Street Magazine in October 2004. Rumpel's uncle, Professor Rumprad Guse invented the very 1st ever Grouch computer.
