Advent Calendar pets rarity

[sydm]

When we will know the rarity of the advent pets?

No one knows the exact date. it can take a bit, they usually wait til all (or at least most) december 18th pets are fully grown before giving a rarity update to things, and that can take a while considering some pets can take up to almost 2 months to be fully grown (aka - the UR phoenix)

anyway, they might decide to do things differently this year, but it usually takes a while.
