Rumpel
From Muppet Wiki
Rumpel is the Grouch from Sesamstrasse, the German co-production of Sesame Street.
Rumpel is a green Grouch (originally "Griesgram" in German, lately "Grautsch") with big energetic eyes. He lives in a barrel with his caterpillar Gustav. 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 and Oscar: quite a few critics weren't fond of the American Sesame Street set. German kids did not 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.
At one point, Rumpel had a superhero alter-ego, similar to Super Grover.(YouTube)
