The rainbow path scene is a randomised pile of hilarity from the lazer collection V
Basically Dominic is singing a Deckd tune (which sounds like a new christmas carol) while walking down a rainbow path, this goes on for 3 seconds before a star with a mustache comes down from the sky and FIREZ A LAZER.
- The star is possibly a starman from the mario video game series.
- The rainbow path is possibly part of the track "rainbow road" from mario kart. (rainbow road is also a playable map in the game "Halo Custom Edition")
- He is probably following Nyan Cat.
