Everyone in Who-ville is celebrating and singing, and who could wait to join in… The Grinch!

With a heart three times bigger and a desire to show the residents of Who-ville that he has changed, could the Grinch's award-winning Christmas tree be the perfect way to prove it?

Play as the Grinch and make giant leaps through snowy 3D worlds, collecting ornaments to make your tree shine brighter with every step.

Overcome platform challenges, explore every corner, and use the delightful gadgets you find to advance through each level.

Use the snowball machine to freeze nasty foes, launch yourself with your rockets, and reach new heights with your jetpack.

Each level is full of festive adventures. Leap into the Grinch's cave, avoiding hanging stalactites and sliding down water slides.

Conquer the slippery ice of Mount Crumpit and the giant snowballs. Find your way through tall trunks and bouncy mushrooms of the Who forest.

Explore Who-ville, jumping over floating platforms and eavesdropping on the cozy homes of the Who-ville residents.

Use candy to break objects and release sparkling ornaments to decorate the Grinch’s Christmas tree and Who-ville square.
