The Grunges started out as enemies of Teddy and his friends for squashing their vegetables. Gimmick had thought they were weeds???! They apologized and when the Grunges recognized that one of the travelers as Prince Arin, they invited all of them to their village for lunch. The Grunges love their music hence the term "Grunge Music", but they are easily tempered. Yet, they are still good friends of Teddy's and they are still considered to be the "coolest" characters in Grundo.
