Shelf Relay is an online video game on the Australian Cartoon Network website. It is based on the webseries.
In July 2017, the game was put on the official Grossery Gang website.
The game is played with the up arrow key and the down arrow key. Using the up arrow key to jump and the down arrow key to roll, the player takes control of Egghead, Pizza Face, Rocky, Doc Broc, and Sparkles in a relay race, dodging various food obstacles.
Hitting any obstacle ends the game, while finishing the course as a character automatically tags the next one to play as.
