It’s a giant machine that has a control panel in front of it, with many choices of different suits to have put on. The suits can be Pokémon themed, animal themed, a fur-suit, spooky themed, silly themed and etc. If a suit is chosen of a pre-existing character the person with the suit will gain the personality and mindset of that character, including Pokémon, if it’s an animal though they act like that animal and if it’s a fur-suit no mental changes happen. It’s a mystery how this machine works.
