Octonauts (2010)

Episode Overview

The Octonauts trace a path of deep-sea wreckage back to its origin: an abandoned ship drifting crewless on the surface. Strange ghostly sounds seem to haunt the vessel, but a quick look beneath the waterline shows the culprit—hundreds of barnacles clinging to the hull. When the ship floats into waters too cold for the barnacles to survive, the Octonauts must figure out how to tow it back to warmer seas before it sinks or breaks apart.
