Nintendo is reportedly teaming up with the fast-food chain at its UK branches to promote the launch of its upcoming console Switch.

The information leaked to Nintendo Life by a regular unknown informant has revealed the marketing notes sent to inform staff of its Super Mario Happy Meals promotion which is expected to run from January 11 to February 7, 2017.

The Happy Meals are expected to contain Mario character balloons, activity sheets and foldable paper figurines.

Meanwhile children and adults alike will be challenged to find the hidden Yoshi on the meal boxes.

It's not the first time that Nintendo has teamed up with a major food chain ahead of a promotion - Krispy Kreme paired with Nintendo in South Korea to create Pokemon doughnuts for Pokemon GO and some Nintendo restaurants in Osaka and Tokyo serve pancakes in the guise of Kirby.
