[Will can't help but grin at the preening; it's kind of endearing, honestly. Clearly he needs to flatter Magolor more often, huh? Although is it really flattery, if it's just the truth?]

Shiny Pokémon are Pokémon that are a rare color for their species! I guess there's no reason things like animals and humans and Halcandrans can't be shiny, too..... but humans have so many complexions and hair and eye colors I don't know how you'd even tell.
