You are Spanner, a unique little fiddler crab. Unlike other crabs in your clan who are mostly red, you were born blue. You have been outcast from your clan and sent off on your own. On your own you don't stand a chance in the world. You need to find a way back in.
And you find it. You must win the annual Crab Castle Build-Off, a competition that is held every year by Spanner's former clan. The object is to build a castle that would be fit for a king crab. The reward for winning such a competition is to become the King for the year. You set out to win the competition and beat the best of the best in the world of professional Crab Castle building.
