Diego is out exploring volcanoes when suddenly, Alicia calls him on his Video Watch and tells him underwater volcanoes are about to blow!!! There are some trapped animals we've gotta save before the volcanoes blow! Giant Octopus can help Diego find the trapped animals and volcanoes in the deep ocean! Along the way we follow Giant Octopus through an underwater ocean garden, squirt purple ink to get away from the Sperm Whales, and dig, dig, dig the animals out of the coral caves so they can swim up, up, up, just before the Ocean Volcanoes blow!!!
