"Refund the World" is a song sung by Gumball and Darwin to try to convince Larry to give them a refund for a game in "The Refund." Before the song starts, in the video Gumball explains that "Jimmy" (Anais) didn't get a refund from the store manager, and now lives in a shoebox. Larry found it very sad, but still ended up not giving them a refund due to the store manager. The lyrics are credited to Mic Graves and Richard Overall.
Darwin: Refund the world! Refund it sooner!
Gumball: Uphold the rights that little Jimmy had as a consumer!
Darwin: Now he's living in a box~
Gumball: He's a victim of deceit~
Both: And even though he still had the receipt!
- This song is a parody of the famous charity song "We are The World", which was sung by many famous singers.
