Darkmoon BalloonAnd those are just the new pets!
There are tooltip changes to the 4 Winter Veil pets that should be noted. What the changes mean, I'm not sure yet. Some of them sound as though they can only be summoned during a certain time of year, but on the other hand, it could just indicate that when summoned outside of their designated holiday they'll look or behave differently. Also note that they will no longer require snowballs to summon!
