Secret of the Miloganda (ミロガンダの秘密 - Miroganda no Himitsu) is the 5th episode of the series, Ultraman. This episode aired on August 14th, 1966.
A group of scientists and reporters have went on an expedition to Oilis Island, and find a rare Miloganda plant, but were almost attacked by a huge green plant-like monster.
One night, a Car crashes beneath an overpass as a result of slipping on an unusual green substance on the Road. When the driver gets out to see what happened though, he is attacked and eaten alive by a green plant-like monster! The Plant Monster also invades the home of a scientist and eats him alive too! The next day, news of the two men's passing (whom were revealed to be a reporter and a geologist respectively) gets out to the Science Patrol, and Ide and Arashi are sent to investigate the home of another one of the Plant's victims prior, Dr. Yamada, while Hayata and Captain Mura go to investigate the crimie scene. Arriving at the scene with fellow scientist Dr. Iwamoto, Iwamoto informs Hayata and Mura that the green substance is a type of Mucin, but it filled with Chlorophyll, revealing that whatever killed both men is both Plant and Monster at the same time.
Meanwhile in the Omuro Highlands, Ide and Arashi visit an aquarium where Dr. Yamada use to work as a Botanist, studying plant life. There, they learn from one of the Doctor's former assistants, Miss Maki, that Dr. Yamada and several other scientists and reporters (including the reporter and the geologist from before, a zoologist, a photographer, Miss Maki, and Dr. Yamada himself) had went on an expedition to Oilis Island sometime ago, where they discovered a Flower known as a "Miloganda," before they were killed. Learning that both the Plant is gone, and that the zoologist has been killed during their investigation, Ide and Arashi return to the Science Patrol to inform Dr. Iwamoto of what they learned. After learning from Iwamoto of the Monster's Mucin trail, they deduce that Dr. Yamada had used Radiation to work on both the Miloganda and his Plants for research, and thus believing that it had an adverse effect on the Miloganda, turning it into the Monster they are searching for.
With the photographer being all that is left of Dr. Yamada's expedition team left to question, the Science Patrol go to visit her for information. The Photographer, named "Setsuko Hamaguchi," reveals that during their expedition, they were attacked by the same Plant Monster in the same vicinity as where the Miloganda was located, revealing that the Plant Monster is an adult form of the Miloganda, and that when Dr. Yamada used radiation on the flower, it accelerated it's growth, transforming it into the same Life-Form that has been killing people. Knowing that the Monster will come after her, the Science Patrol agrees to watch her through the night to ensure her protection against the Life-Form. Sure enough, the next day, Arashi is attacked by the Monster as it attempts to eat him. Luckily, the rest of the Science Patrol arrives on the scene, rescuing Arashi and firing on the Life-Form with their Superguns, knocking it into a nearby Pond.
Unfortunately though, later that night, the Science Patrol learns that the Monster is still alive and is attacking Marunouchi. Having grown to enormous proportions due to absorbing the energy of the Science Patrol's Superguns, the Life-Form (dubbed "Greenmons") begins attacking the city. This time, Greenmons easily shrugs off the Science Patrol's opposition and manages to paralyze Arashi during its rampage. Luckily, Arashi is rescue by Hayata, who takes him to a discrete location so that he can transform into Ultraman to fight the Life-Form himself. Greenmons immediately attempts to subdue Ultraman by paralyzing him too, but Ultraman manages to fight through his paralysis, and he strikes Greenmons with his Specium Ray, setting the Life-Form ablaze until all that was left of the Plant Monster are Ashes.
With their task fulfilled, the Science Patrol immediately heads out, only for Ide to comically ask where Hayata has disappeared to...
