Stone

The Stone is a Mythical pet introduced with the 16.5.0 update.

Appearance

It is simply a gray rock. It has a pair of eyes, a small mouth, a pair of stony eyebrows and a tiny flower on top of it.

Since this pet does nothing at all, do not use it, or only use it in Sandbox mode.
If you want a pet that could attack, use another pet.
Do not upgrade this pet, either, as it does not attack.
This pet does not work as a bait against enemies in Arena or Campaign.
This pet actually does damage upon death, but still, do not use this pet.

It has low health meaning that it can be killed in around 2-5 shots from a Primary weapon.
Kill it when using weapons with a high fire rate and great accuracy, such as the Crystal Laser Cannon.
Don't be worried about the pet attacking you since it won't do anything at all. Feel free to shoot it.
- Still, it is not recommended to attack the pet as you can be spending the time to attack players instead.
- Nevertheless, killing it is not recommended, as it will detonate itself upon death. The pet does not attack, therefore it makes killing it a waste of ammunition and also distracts you.
  - Regardless, you can earn 5 points for killing it so do so if you are desperate for points.
If you don't know where the pet's user is, follow this pet until you find him or her.

It is the only pet that does nothing while living (It explodes upon death).
It behaves the same way in multiplayer as it does in Sandbox.
It may be a reference to Patrick’s pet rock from the T.V show, 'Spongebob Squarepants', or the 'Pet Rock' toy, which was popular in the mid-1970's.
For a period of time, it was described as having "Consecutive Explosions" as an attribute in the Armory, but it has been reverted.
