Green Helper Box



Green Helper Box summons and dismisses Father Winter's Helper, a small gnome companion dressed in festive green garb who follows you around, meaning it is a non-combat pet and will not aid you in battle.

The Green Helper Box is one of the four possible pet items you can receive as gifts under the big tree in Ironforge and Orgrimmar during the Feast of Winter Veil seasonal event.

Even if you did not obtain this pet in a present, they can often be found in the Auction House throughout the year at highly inflated prices.

There is also a red variant of this pet summoned from a Red Helper Box.

Pet Journal
These off-season allies work tirelessly to prepare for the Feast of Winter Veil, and would appreciate not being disturbed the rest of the year.
