Beneath the Waves - Incomplete

So I entered the Beneath the Waves Keyframe Challenge, but life got in the way and I wasn't able to finish all four. I came up with a story that consists of a young crab who's father was killed by a giant Octopus. His grandfather has been telling the young crab the story of his father's bravery for years....One day, the crab decides to go on a journey to find his father's killer to avenge him. He finds the giant Octopus in his lair and lures him out for a climactic battle. I think I'll try to finish the fourth one just because I liked the idea so much.
