I need a javascript animation

 A boy is sailing on a boat and he arrives at a deserted island, he gets off the boat and grads a shovel from it and walks to a tree under which a big sign “X” can be found, he digs up the sand right where the sign is and jumps inside the hole. Afterwords, a big treasure chest comes out of the hole and the boy also gets out, he then pulls out a key and open the chest. The chest appears to be full of gold, the end.
