L.A.-based mobile developer Jam City has joined forces with Dr. Seuss Enterprises and White Space Entertainment to bring the Grinch into the mobile gaming world for the first time. Throughout the month of December, bubble shooter game Panda Pop will feature the classic Dr. Seuss character.

Panda Pop now features Grinch-themed artwork and levels, in-game events and prizes, as well as a Grinch costume for the game’s Mama Panda character and a branded starter pack for all players.

With more than 100 million downloads, Panda Pop is free to play and available on mobile devices via the App Store and Google Play. The game’s Grinch takeover comes as Dr. Seuss’ classic holiday book How the Grinch Stole Christmas! celebrates its 60th anniversary.

Jam City was established in 2010 by former MySpace co-founders Chris DeWolfe and Aber Whitcomb, along with ex-20th Century Fox executive Josh Yguado.
