Diamond Academy

Diamond Academy is an academy in Diamond City that Penny attends in WarioWare: Smooth Moves.

The auditorium of the school is seen in the game. It was the place where Penny competed in the Great Invent-off against her grandfather to see who was the bad inventor. For that particular event, there was a boxing ring and an audience that seemed to be made up of Mr. Game & Watches.
