A couple of days ago, Rovio released The Croods, a practically fowl-free resource management game based on DreamWorks’ upcoming animated film of the same name. But it turns out that Rovio’s The Croods is not the only official iOS tie-in for “The Croods.”

Apparently, there’s also some “pre-hysterical” fun to be had with the iOS app The Croods: Crood-ify Yourself:

The Croods invite you to Crood-ify Yourself! Ever wonder what you would look like as a prehistoric person? Upload or take a photo to Crood-ify yourself and your friends and family! Share your Crood-ified photo on Facebook/Twitter and post your Crood-ified photo on Instagram with #TheCroods for the most Croodaceous look in your social network!

Essentially, The Croods: Crood-ify Yourself is a photo booth app that lets you put your face into any of the featured characters from the movie. You can choose to be Grug, Eep, Guy, Thunk, Ugga, or Sandy.

The app also lets you choose from four prehistoric backgrounds, three skin tones, and three hair colors. The app then lets you save your Crood-ified photo or share it on Facebook, Twitter, and Instagram.

The app is rather silly. But hey, maybe you and your kid would end up having lots of fun Crood-ifying your silly faces with the app.

Compatible with iPhone, iPod touch, and iPad running iOS 6.0 or later, The Croods: Crood-ify Yourself is available now in the App Store for free.

Rovio’s The Croods is also available in the App Store for free.

DreamWorks’ “The Croods” is set to hit theaters on Friday, March 22. The Croods: Crood-ify Yourself includes a link to Fandango, where you can get tickets for the movie.
