"Aberdeen" is a song from "The Bumpkin," appearing to be a folk song from the countryside. Idaho gets the Wattersons to sing along with him, then at the end of the episode, Gumball sings it as an elegy for Idaho, with the rest of the family joining in.
Lyrics
Idaho: Aberdeen, in the wind
In the field potato
[Lyrics are repeated by the Wattersons]
Gumball: Aberdeen, in the wind
In the field potato
Wattersons: Ahh whooo...
Ahh whooo-ooooo...
Idaho: Whooo!
Trivia
- Aberdeen is actually the name of several real-life cities, most notably the one in Bingham County, Idaho, in the United States (with this presumably being the one the song references) and the one in Scotland.
