You're a deep-sea diving elephant on a mission to find pearls in oyster shells and escape from your terrible life in the circus! Your objective is to collect the oyster shells in the underwater cave in one continuous line and then get your trunk to the exit.
The tricky part is not crossing your trunk at any point or blocking it into a corner! Look out for munchy fish. They just love eating elephant whenever they can. You can squash the fish with the tip of your trunk, but avoid getting bitten on the side.
