The "Sea Rabbit" actually looks a bit cute. Its body is grayish-white, with three pairs of fins for paddling and a pair of rabbit-ear-like protrusions, drifting slowly with the current.
Until it opens its big mouth to reveal sharp teeth. Congratulations, you've just hitched a ride. This driver's sense of direction is really not great; it has only one driving style: upside down and reversed left-right.
Once ashore, this creature becomes much tamer. If you can't wait, you can light a fire and roast it.
