The giant wolpertinger pouch is an item made by players during Wolf Whistle. Players create this item out of the embroidered pouch, rare summoning items, ancient wolf bone amulet, and white hare meat. Players use it to summon a giant wolpertinger to scare off the trolls Wolf Meat and Wolf Bones to save Bowloftrix. If you make 2 giant wolpertinger pouches during the quest and use the second one on the Obeslik you gain 2,000 summoning experience.
