Stalker

The Stalker is a predatory life form hostile to the player, other life forms and sometimes even other Stalkers. They are life forms, belonging to the fauna category.

They drop stalker teeth as they swim around, especially while carrying things in their mouth. A good tactic to get teeth from Stalkers is to drop a piece of metal near them and wait for them to get it. There is a high probability they will drop a tooth then.

Stalkers can be found in multiple biomes, predominantly in the Kelp Forest.

Behavior
Stalkers have a fondness for scrap metal, and have a tendency to pick fragments up and gather them in one spot. Stalkers will also fight about them from time to time.

If the player breaks a chunk of limestone or similar and leaves the metal chunk that emerges from it be, nearby Stalkers will pick up that one as well.

Interaction with the player
Despite their generally aggressive attitude, Stalkers are actually quite intelligent creatures.

If the player approaches a stalker with a fish in their hand, the stalker will swim up to the player and eat the fish. The Stalker will then be friendly to the player. It will pick up pieces of scrap metal and drop them in front of the player as "present".

Stalkers will also take scrap metal from the player's hand and put them into their hoard. This will also tame the Stalkers. However, they will not start to bring the player metal.

Once the Stalker has turned hostile on the player, it will not accept fish or pieces of metal any more. Thus, the player must equip the item in question before approaching the Stalker.
