Though I have to ask, what about glittery pink? ;p

Since the entire cast of Twilight is composed of Suvians and/or bits, this therefore applies to everyone in the Twiverse as well, including off-screen characters. Ergo, since the sparklevamps must have drunk human blood at some point, they must have consumed enough Glitter to sparkle!

...Come to that, it wouldn't half surprise me if even the animals in the Twiverse have some amount of Glitter in their bloodstream. Maybe the Twiverse is just a factory for the more mundane CAFs ("Mundane" in this case meaning something like a normal wolf, not a magical talking spirit wolf with wings).

Just as a note, has anyone else associated the term "bits" (bit characters) with "Kibbles 'n' Bits"?
