Sheldon the Hermit Crab needs your help getting home. Drag Sheldon around to navigate various levels of increasing difficulty. Getting to each levels portal will not be easy. There will be things blocking Sheldons path. Drag your tools to cut seaweed, smash rocks, dig out sea urchins and remove star fish.
Along the way protect your little crab buddies and learn to use your shell to help clear the way.
