Boo Brigade Return

From the Super Mario Wiki, the Mario encyclopedia
Boo splitting into multiple smaller Boos, while using Boo Brigade Return

Boo Brigade Return is the Defensive Power Shot used by Boo in Mario Power Tennis. Boo spins around, becoming bigger, until it splits up into many smaller Boos, searching for the ball to hit it back. Curiously, the Boo brigade does not show the "real" Boo with the glowing racket, but it appears once it finds the ball.

The glitch

Sometimes, a glitch occurs where the Boos' faces while they are performing this move will be messed up.
