Factory (tennis school)

Factory is one of the four schools competing in the Island Open in Mario Tennis and Mario Tennis: Power Tour. Factory was initially best known for the Costello Brothers, A. Coz and B. Coz. Later, their younger brother, Willy, became their best player, as the older brothers become coaches for Factory. Factory is expected to win by most spectators of the Island Open because the Costellos always make it to the finals.
