Isn't that The Yodel Song?
From The Lost Media Wiki
< The Ren & Stimpy Show (non-existent unused Kurt Cobain song for Nickelodeon animated series; 1990)
I have heard multiple times that this song he made for ren and stimpy is the yodel song. Idk if the truth is that it's that one or that it just never existed but that sounds like it's worth a mention.
