Professor Inkling and Kwazii go to the Midnight Zone to plant deep sea corals when they are attacked by two hungry gulper eels. Then an underwater tremor occurs and Inkling and Kwazii fall into a fissure formed by the tremor. They are wedged in by rocks and the fissure is too narrow for a gup to pass through. That's when an Octo-Max Suit - Tweak and Dashi's latest invention - comes in handy. The drill saves the two.
