Colossus: Crab

To test my design mettle, I created a boss that would have fit into the game Shadow of the Colossus. Wander would have to let it try to crush him with it's claw which would then get stuck in the sand. He could then climb up the claw onto the back and work around to the centre as it spun (holding onto the seaweed) to stab it's back. Finally it would recede into the water until Wander let go before climbing back onto the shore to attack anew.

SotC is my favourite game of all time. Designed to perfection.
