The Hovercraft floated in water, and could drive on land as well. It could carry several figures into battle, drop 'depth charges', and could fire a one-man sled out of the front.
The WHALE came with "Cutter" and his filecard, accessories, and blueprints/instructions for assembly.
Due to it's many small parts, the Hovercraft was difficult to keep in one piece, but Hasbro offered it many times through mail-order flag points as well.
