Octonauts

S05E02 Bluefin Tuna

When the Octonauts cross paths with a school of migrating tuna, they notice that one fast swimmer, Tina, has fallen behind—and she's hurt. A hook is lodged in her mouth, leaving her too weak to swim. Once Peso patches up her wound, the crew promises to get Tina to the tuna spawning grounds before egg-laying season ends. Fortunately, Tweak's newest gup, the Gup-R, is her speediest creation yet. They tow Tina with it—until the battery runs out. Now how will they ever catch up with her school?
