Forbidden Forest - Horklump Hollow Collection Chest This Collection Chest can be found in the small dungeon called Horklump Hollow, found on the border of Hogsmeade Valley just to the west of Upper Hogsfield on a high bluff overlooking a bandit camp.

There is a cave to the north of Hogsmeade called Horklump Hollow that, predictably, is full of Horklump Juice gathering spots. Players can find it on the map above, but it is not without its dangers. Specifically, there's a powerful Mountain Troll at the end of this dungeon guarding a majority of the Horklump Juice.

Thankfully Horklump Juice (which is the item that can't be grown for the Wiggunweld Potion) can be farmed in a dungeon just north of Hogsmeade.

Horklumps grow outside three Treasure Vaults located in this region. The regrow time for Horklumps is three game days, and each harvest yields one juice.
