Earthworm! Go!

Momo and Jiji watch the Kito Family direct the Mongolian Death Worm to spit sharks at the Typhoon Human, and Jiji briefly marvels before remembering the creature is still an enemy. When Momo wonders how the worm endures the freezing air outside, Naki scolds her for doubting a beast that lives underground. The pair press on with their assault. Turbulence from a shark striking the plane flings Momo out of the cabin, and Jiji races after her but cannot reach her in time; Unji, in his Umbrella Boy form, snags her with his umbrella instead. Still blind, Unji asks Futa to guide him, and Jiji grabs Unji's hand when a shark knocks the lodged umbrella loose.

Seeing the Typhoon Human hold firm, Naki asks how many more sharks they must hurl into it, though her sons garble Momo's order to keep going. The Typhoon Human then inhales two sharks through its nose and fires them at the Death Worm, skewering it clean through, stunning everyone. To stop the worm from drifting off, Momo grabs it with her psychic hand and rises to its mouth, making it glide like a carp streamer. Jiji notes they have drifted from the plane, but Momo assures him that beating their foe and arriving in Shimane means climbing into the stratosphere to strike the eye directly.

Momo nearly tumbles from the plane, yet Jiji and Unji join forces to rescue her. The Typhoon Human slices the Tsuchinoko Hatchling in two by firing sharks from its nose. Momo, Unji, and Jiji grab the hatchling, which Momo converts into a floating windsock. The trio rises through the stratosphere, aiming to crush the typhoon's eye.
