[Blue Violet]

I have looked at the national website and all, but I was wondering....
1) Why is the teddy bear the "unofficial" mascot?
2) Do some chapters have a local mascot? (I know Gammi Phi Beta does this-they have national colors & a symbol and local colors & local mascot)
3) Is there a crest or coat of arms?
4) Do the colligiate chapters rush with NPC? ( I know Beta isn't NPC-but that doesn't mean you can't be part of NPC)

Thanks!
