"The Decorating Song" is a short song Finn and Jake sing in "Her Parents." In the song, Finn and Jake try to look like Rainicorns. BMO is seen with rainbow colors on it, but it does not sing this song.
| Finn and Jake: Ketchup! Mustard! Red and yellow!|
Jake: Lady's parents, I say hello!
I'm the fellow for your daughter
Please forget the wartime slaughter!
| Home improvement, decorations.|
Help me impress her relations.
Finn: Sugar Bears, and rainbow jelly.
Jake: Spread those colors on my belly!
| Finn: On the floor and up the log.|
Jake: Please don't notice I'm a dog!
