"Jingle Dance" is a song from "The Mess." It is sung by Gumball when he tries to get an orange juice for Polly. The song gets interrupted when Darwin yells and the scene cuts to him mistaking an actual blue cat for Gumball.
Gumball: Hey! Jingle dance, jingle dance, jingle in your face!
Chilling out like sauerkraut who just caught himself a trout, hey!
Jingle dance, jingle dance, jingle in your face!
- This is an obvious reference to the Christmas song "Jingle Bells," as it is sung to the same tune and contains a somewhat similar chorus.
