Where players make their own eggs in Studio and post them with the tag 'Egg Hunt 2016'. And think of the takes as votes. Sorta like the shirt competition they had. One with the most votes might get their egg in Egg Hunt 2016.
Free models, some wouldn't be for the hunt, many complications not listed. You need to think about problems before you blindly release a event.
Plus they will just make a devhunt anyway
