Peso narrowly escapes when a hungry great white shark tries to eat him. Despite this he wants to help him after he injures his fin against the Octopod. The Octonauts use the Gup-X to turn the shark upside down and induce tonic immobility whilst Peso bandages him, but he comes round and in the end they escape by feeding him Tunip's fish biscuits to satisfy his hunger. In the end, the shark isn't hungry and says that he loves Peso and Kwazii because they bandaged his injured fin. The shark seems to have a faint Scottish accent.
