The Great Algae Escape

recommended age Unlock co-watching from 3

Captain Barnacles and the Octonaut crew investigate an underwater area choked with algae where the crabs and lobsters are too sick to move. While they explore, a group of crabs hijacks the Octopod to escape the polluted water. The crew chases down their ship in a gup vehicle, hears the crabs out, and traces the algae back to a leaky pipe. They fix the pipe, clean the excess algae, and the creatures return to health.

The Giant Squid

recommended age Unlock co-watching from 3

While Professor Inkling bakes fish biscuits on the Octopod, the Gup-A is grabbed by an unseen creature near a set of underwater caves and escapes coated in slimy ink and ringed sucker marks. Inkling recognises the marks as belonging to his distant cousin Irving the giant squid and joins Captain Barnacles, Kwazii and Peso on a search mission. The crew explores the dark caves, mistaking a manta ray and an eel for the squid, until Irving follows the smell of the biscuits and reunites with his cousin. Irving explains he was simply hungry, eats several baskets of biscuits, and the episode ends with a posed family photo at the Octopod.
