Factory is one of the four schools competing in the Island Open in Mario Tennis and Mario Power Tennis. Factory is best known for the Costello Brothers--A. Coz, B. Coz, and their younger brother, Willy. Factory starts out not expected to fare well, but the Costellos always make it to the finals, much to the surprise of most spectators.
