Selphie reminds me of this person in the manga movie "Visions of Escaflowne" a sort of cat-girl, extremely hyper personality and attitute. How can you not like someone like that?

Dollet Communications Tower:
Selphie is acting hyper again!

Zell: "Watch out or you'll fall"
Selphie: "Like I'm really going to"

And ofcource @ the orphanage when they are playing with fireworks and start dishing Zell (@ least I thought it was Zell)
