Did you know that Robert Rodriguez and BlackBerry are collaborating on a new short film called Two Scoops? The movie follows the adventures of two monster hunters that pose as ice cream vendors during the day. The film is pretty much finished, but he’s letting the fans add the finishing touches.

Rodriguez announced this week that he’s now accepting submissions for the monster that the two hunters will fight at the end of the film. Unlike the past few contests, aspiring designers don’t have to do a lot here. All they have to do is create a simple sketch of the monster. After that, Rodriguez’ designers will take over and bring it to life.

For a chance to have your monster appear in Two Scoops, you just have to submit your design to BlackBerry’s Keep Moving promo site.
