The Critter Gitters find themselves on a wild sea adventure involving a whale, which has come in too close to shore. Kaitlin bravely skippers a Hobie Cat through the dangerous ocean currents to help save the whale. In the meantime, the rest of the Critter Gitters are left on their own to sail a catamaran for help. Using nautical skills, common sense and Critter Gitter technology, the Critter Gitters once again help save the life of yet another animal.
