If you are a fan of ponies like myself (and I would be surprised to find other people reading this, unless they happen to just be passing by), you might have stumbled upon artwork of Rarity fighting a giant crab. Well, one of the people behind some of such arts and comics is holding an art contest! Points are the reward, but the crab is the point! Just make some form of art with that giant crab whose reference sheet is provided in the journal linked below, and if it's good enough, you might get a bunch of dA points! And that means free premium membership or other nifty things.
Anyway, without further ado... Journal page with rules and details here!
