Scientists have begun to conduct research involving the enlargement of bees used to produce "Honey Jellion," a super Royal Jelly, one million times more potent than normal. If consumed in concentrated form, this nutritional agent poses a serious side effect: gigantism. A researcher at the station returns one day to find that someone has broken into his greenhouse and destroyed this larvae. The perpetrator -- a jealous rival -- takes the remnants of the insects and allows his mole to feed on them. Turning gigantic, this beast "Mongula" threatens to wreak havoc on the surrounding area.
