Synopsis

Upon encountering a blue whale with a wounded tail, the Octonauts mobilize to prevent its submersion. Employing a large net and Octofloats, they strive to keep the magnificent creature afloat. Simultaneously, Peso and Tweak work together to fashion a supportive brace for the whale's tail, while Kwazii, Dashi, and Shellington search for sustenance. However, when the supporting net gives way, the Octonauts must initiate an urgent free-fall rescue.
