As Shellington was learning about some shy garden eels at night in the Gup-E, he falls asleep as a bloom of sea nettle jellyfish covers up the entire place. The Octonauts discovered that Shellington is still in the ocean in the Gup-E with low power. Captain Barnacles, Kwazii, and Peso try to rescue him with the Gup-A, but there are too many jellyfish blocking their path. As they swim back to the Octopod, Barnacles gets stung on the paw by a jellyfish, so it is up to Kwazii and Peso to save Shellington, and Barnacles has an idea... He dumps more vinegar for the treatment given by Peso, which hurt a little, but recovered instantly, runs to the Gup-D, drills a hole is the rocky cliffs, and rescues the three, as they were about to be pulled into the ocean by a sea nettle. A huge jellyfish appears at the HQ windows, and the Octonauts enjoy a morning break, admiring the wonders of a jellyfish bloom.
