From Bulbapedia, the community-driven Pokémon encyclopedia.
The Ferroseed Research Institute (Japanese: テッシード研究所 Tesseed Research Institute) is a facility located in a town between Icirrus City and Opelucid City. At the institute, research is being conducted on the moss produced by Ferroseed, which has qualities that enhances a Pokémon's abilities. The director and leading researcher of the institute is Professor Malveaux while Case works there as a scientist.
The Institute specially researches different types of moss from different locations, such as from ores from the outskirts of Driftveil City and from rocks from the Desert Resort. They are also conducting research on moss contracted by the Ferroseed while gaining power from electric rocks from Chargestone Cave.
In Crisis at Ferroseed Research!, Ash, Iris and Cilan met up with Georgia who was going to the institute to enhance the powers of her Vanilluxe. Ash, Iris and Cilan decided to come with Georgia. In the institute, they were greeted by Case, who gave them a tour through the building. Everything went drastically out of control, however, when the moss of the Ferroseed suddenly managed to break free of one of the laboratories and began to cover the complete building and its surroundings.
While the others managed to escape, Iris became stuck on the institute's roof with her Axew, Ash's Oshawott and Georgia's Vanilluxe. They were about to be attacked by the ever spreading moss when they discovered the moss was vulnerable to Ice-type attacks. With the help of Vanilluxe, Georgia's other Ice-type Pokémon Beartic and Officer Jenny's Swanna they managed to stop the moss from growing and save the institute.
