The Octonauts are getting ready for their annual seaweed feast near the Galapagos Islands. But when a trio of salt sneezing Marine Iguanas raid the Octopd and steal the red seaweed, Barnacles, Kwazii and the rest of the Octonauts sound the alert and head off in pursuit. With a flap to lift on each page, join the crew in a game of hide and seek... Can they get their seaweed back in time for the feast?
