Microsoft has created a set of four pizza-scented Teenage Mutant Ninja Turtles-themed Xbox controllers to celebrate the premiere of TMNT: Mutant Mayhem.

Announced on the Xbox Wire, the "ooze green" controllers come with a built-in scent diffuser shaped like a slice of pizza perched behind the gamepad. There are four different designs to accommodate the four different turtles but only one flavour of pizza scent on offer.

Fans of the Teenage Mutant Ninja Turtles or gross controllers can enter a competition to win a "limited number" of the gamepads by following the Xbox Game Pass Twitter and retweeting the sweepstakes tweet by August 13.

"Satisfy your hunger for kicking butt with the world’s first ever pizza-scented controller," reads the Xbox Wire post. "Designed to deliver the smell of the Turtles’ beloved meal to your game time, these exclusive Xbox Wireless Controllers come with a built-in scent diffuser shaped like a slice of delicious New York ‘za.

"The controller comes in four variations, each representing the signature colours, weapons, and personality of a Turtle brother: Leonardo, Raphael, Donatello, and Michelangelo."
