Rally Challenge (Intermediate)

Rally Challenge (Intermediate) is the twelfth mission in Mario Tennis Aces, taking place in Detour.

Layout
A Boo comes to Mario and Toad and tells them that he has a Mirror Racket to give them, but he won't give it for free, and challenges Mario to a match.

In the match, Mario must keep rallying the ball to the Boo. Each individual rally is worth one point, and Mario must score 300 to win. Mario scores ten bonus points for the tenth consecutive rally, twenty points for the twentieth consecutive rally, and thirty points for every ten subsequent consecutive rallies. The mission ends in a failure if Mario misses a ball three times.

Afterwards, Boo gives Mario the Mirror Racket, and says that from now on he is on his side, and won't even "boo" him when he plays.
