The Octonauts

Kwazii and Dashi become entangled in a strange deepsea creature...a siphonophore...and when a geyser blasts it toward the surface, the Octonauts must stop its ascent before it bursts.

The Octonauts venture into a dangerous red hot lava tube to rescue a teeny tiny water bear who doesn't seem to mind the heat at all!

Only Peso can save the day when a cone snail invades the Octopod and picks off the crew one by one with its dangerous harpoons.

When an underwater storm destroys a small reef, which a frogfish and other creatures depend on, Tweak and her crewmates must convert the Gup-F into an artificial reef before another storm strikes.

When a sardine swallows the key to a treasure chest, a humpback whale helps Kwazii track it down.

When a floating garbage patch endangers a flock of pelicans and other sea creatures, the Octonauts and the birds work together to clean it up.
