H.E.A.T. tackles a gigantic mutant shrew-like creature, which has somehow merged itself with an artificially generated, experimental tornado, enabling it to transform itself into a living vortex at will (Elsie wittily dubs the whirling beast 'The Shrewster'). In order to maintain its ultra-fast, whirlwind powers, the Shrewster is forced to rapidly consume three times its body weight per day, thus causing it to greedily devour every organic food source in its path, effectively making it an extremely dangerous menace. Because of its ability to transform itself into an organic tornado, Godzilla is unable to get at the beast, and Tatopoulos ends up trapped in the Shrewster's vortex. However, soon after becoming trapped, he activates a device that Craven crafted, which was designed to dissipate the vortex's cyclonic forces, and this succeeds.
