The Octonauts - Season 3, Episode 16: The Sea Sponge
Trailer
Season 3 completes new tracks, as the sardines swallow the treasure chest key. Now, the humpback whale is a traceable tracker to grasp the moment differently. The litter patch seems to be turning things around a different path and putting the floating around in danger through a group of swans and other marine creatures. Astronauts and birds are still working together to clean up at that moment.
