Penny

How Penny joined the Tourney
At the king's castle, Barney the Dinosaur, Baby Bop, BJ, Justin, Jessica, Andy, and Penny returned the crown to the king to have a Musical Castle Celebration. The celebration was interrupted by Shin Kamiya, who wanted the gang to participate in the coming tournament, the Smash Bros. Tourney. Barney, Baby Bop, BJ, and Penny all left the Rosemont Theatre and headed for Nintendo Land. Shin warned Penny that Winry Rockbell was waiting for Penny at the end of the tournament.
