Laurier -- in order to get blizzard offspring, you either have to breed to another blizzard, or to an animal that is het for blizzard (hence the "in the closet" blizzard comment

) While it's possible for your tang to be het for blizzard, it's quite unlikely unless you actually purchased the animal as such.
Assuming that your tang isn't het for blizzard, what you'll end up with is 100% of the babies being het for blizzard. If you were to breed one of these babies back to the blizzard parent, you would then have a chance of getting blizzard offspring.
HTH
