The Ring of Fire erupts which causes volcanoes to erupt, tremors, and tsunami waves to appear all along the Pacific Ocean encountering the Octonauts, who are all doing their own thing. They use the recently created Gup-Z, (Z1, Z2, Z3, Z4, Z5, Mega Gup-Z, and Gup-Z Mantis Shrimp Mode), to save many creatures, including an Omura's Whale, some Chinstrap Penguins, and many more from many volcanoes around the the Ring of Fire and one giant volcano.
