Grubfoot is an item that may be placed into the player's inventory when Grubfoot is following them during Land of the Goblins. Dropping it will cause him to follow the player, much like a pet does.
Because he cannot be picked up normally, the follower item is not intended to be received by players, but is used as a failsafe measure in the event that the Grubfoot follower is forced into the player's backpack.
Trivia
Despite being named Grubfoot, the item model is in fact Zanik.
