Notzilla

In 1962, the Japanese military successfully eliminates another giant kaiju. Professor Hiro Honda manages to save the creature’s offspring, securing a mysterious red egg and transporting it to Cincinnati, Ohio. Unfortunately, upon landing, he inadvertently sends the egg down the toilet, where it ends up in the Ohio River. The egg, disturbed by nuclear testing, is soon found by Dr. Blowheart and his assistant, Dr. Shirley Yujest. They encounter Professor Honda, who reveals that the egg harbors a living Notzillasaurus Partiontilldon. He warns them that the creature will stay small unless it comes into contact with alcohol, which would cause it to grow exponentially and threaten the nearest city.
