About This Game

Every Who down in Who-ville is jingling, singing and celebrating. And guess who can’t wait to join them… the Grinch! Now, with a heart three sizes bigger, and a wish to show the Whos he’s changed, could the Grinch’s prize-winning tree be the perfect way to prove it?





Play as the Grinch and Jumbo-Jump through snowy 3D worlds, collecting ornaments to make your tree sparkle brighter with every step. Overcome platforming challenges, explore every nook and cranny, and use the clever gadgets you find to get through each level. Unleash the Snowball Maker to freeze mischievous adversaries, launch into action with the Rocket Skates, and reach new heights with the Jetpack.



Each level is filled with festive adventures. Hop through the Grinch’s Cave, dodging falling stalactites and zipping down watery chutes. Conquer Mt. Crumpit’s slippery ice and giant rolling snowballs. Find your way through Who-wood’s towering trees and springy mushrooms. Then explore Who-ville, leaping across hovering platforms and sneaking into the Whos’ cozy homes. Use your candy canes to break objects and release dazzling ornaments to decorate the Grinch’s Christmas tree and Who-ville Square.



Adventure solo or team up in local co-op mode. Together with Max, you’ll have fun outsmarting pesky mice, wild forest bats and other curious creatures. Uncover hidden paths and collect every sparkly decoration you can find to make your tree shine.



Make it a merry day in Who-ville, spread Christmas cheer, and create the most spectacular tree the Whos have ever seen!
