Pet rock

A pet rock can be obtained from Askeladden during and after The Fremennik Trials quest. After the quest multiple pet rocks can be obtained by talking to him again.

Rocks can usually find their own food, and don't often need attention, so rocks are a good choice for a pet. The pet rock is held in both hands, although it cannot be used as a weapon; unarmed attacks are instead used while the pet rock is equipped. The pet rock does not confer any stat bonuses or penalties.

Pet rocks will happily live in the cat basket or menagerie of a player-owned house.

Uses
In the quest it is used to convince Lalli give you some of his golden wool. A Pet rock, cabbage, onion, and a potato are the ingredients to make rock soup, to please him.

Unlike most pets, the pet rock will not follow the player when it is dropped, possibly due to the rock's shy nature. Because of this, it can be used to substitute a player while attempting to open the two-man doors in the Waterbirth Island Dungeon. To get further into the dungeon, a partner has to destroy the door-support from the other side of the ladder, although a special attack of a rune thrownaxe can do this instead.
