We got a lotta stuff here. Okay, from left to right...

Row 1: Headlight gets a look at  KDRaccoon's Leafeon, Dino. She seems to have mistaken him for someone else.
Headlight dashes past in a star-patterned uniform, Expert Belt flying in the wind. I'd be tempted to switch if I didn't like her old one so much.

Row 2: Headlight...serving a can of beans, apparently as a waitress. With that outfit, I'm kind of inclined to ask what restaurant she's working at, exactly.
Headlight in another battle garb. I like the starry one better.
Headlight dressed up as Ulala from Space Chanel 5. Who wants to be Space Michael!

Row 3: Headlight from last year. She don't have no dang accent!
And lastly, Burst and Leppy doing what Burst and Leppy do best. =3
