This year’s collaboration sees The Grinch visit Mama Panda’s Dojo to mess up the holiday. The game has been designed to resemble Whoville and to feature special in-game events and themes, and it will include appearances by The Grinch, his dog-turned-reindeer Max and Cindy Lou Who.

Grinchmas events supporting the collaboration include:

“Last holiday season, ‘Panda Pop’ audiences adored the debut of The Grinch in their favorite mobile game,” says Vanessa Rouhani, vice president, publishing, Jam City. “From the festive artwork to Grinch-themed events, players loved seeing an icon of the holidays in the game. After last year’s response, we’re thrilled to bring even more of the fun, humor and nostalgia of this beloved character to our millions of ‘Panda Pop’ players for this special season.”

The Grinch will take over “Panda Pop” through Jan. 2.
