At the start, Star dances rather frenetically, shaking her hips and moving like a rabbid animal. This somehow made her heart-shaped cheek markings glow white.
Marco soon joins the dance, moving in a slow, smooth ballet-like steps, which made his beauty mark glow as well.
The two teenagers joined in the dance, and as Marco struggled to keep up with Star's frenetic pace, she soon takes the upper hand and hugs Marco, successfully fusing them together.
The resulting fusion is a girl like Star, and also shares her dress, long hair and cheek markings, and from Marco she gets a tanned skin, brown hair, a pair of beauty marks next to the heart marks and a red vest.
"STARCO!" the fusion shouted in a voice combining both Star and Marco's tone.
