Okay, I'll be using Person Man, my Mr. Mime, in addition to Starman Jr.

Person Man, start with Seismic Toss. Throw Starman Jr. into the rafters. Starman Jr., you grab onto the ceiling - any outpost will do. Next, you should both fire Shadow Balls at each other - have them explode in midair. Finally, Starman Jr., send down a weak Silver Wind - enough to make Person Man all sparkly but not enough to obscure him. Person Man, create a Reflect while striking a cool pose - the Reflect should refract the Silver Wind around you, amplifying its sparklyness.

Person Man: Seismic Toss (Starman Jr.) ~ Shadow Ball (Starman Jr.'s Shadow Ball) ~ Cool Pose Reflect
Starman Jr.: Grab Hold (rafters/anything) ~ Shadow Ball (Person Man's Shadow Ball) ~ Weak Silver Wind (Person Man)
