Yôichi Manoda

One day, a shrimp fisherman catches a large tadpole. Dr. Yano discovers that the captured animal is not a tadpole, but a life form that originated in some chemical way in the polluted water of the bay. During experiments, the tadpole grows very rapidly and escapes, returning to the polluted water of the bay and growing into a monster. There happens to be another monster in the bay: Godzilla, in which the tadpole Hedra engages in a fight with.

An ever evolving alien life-form arrives on a comet from the Dark Gaseous Nebula and proceeds to consume pollution. Spewing mists of sulfuric acid and corrosive sludge, neither humanity nor Godzilla may be able to defeat this toxic menace.

A short compilation film made to be shown at Takarazuka Family Land which takes footage from several Showa era Godzilla films.
