From The Chobots Wiki

Magic was a feature in Chobots that referred to unique animations that could be played in-game by moderators, often during parties, and players who owned special magic items. In addition to these animations, magic allowed moderators to gift items to players by having them fall from the top of the screen, during which time players could click the items to collect them in an event known colloquially referred to as "rain," and modify the appearances of rooms, such as by changing their color and brightness.
