Five eh? Well, let's see...

Possible to own someday:
Albino (working on it)
BumbleBEE! (about 3 years from now)
Lesser
Caramel Albino
KillerBee

Probably IMpossible, but I really like them:
Pastel Coral Glow
Lavender Albino
Pastel Clown
Spinner Blast
Axanthic KillerBee

Hmm, are we detecting a yellow theme here?
