Lizard Doggo

The Lizard Doggo is a short reptilian dog, red in color and about the height of an engineer's knees. It wanders around and will run from engineers, but can be baited with Paleberries. It is widely viewed as the game's mascot after its initial appearance in the teaser trailer, and was therefore the first thing ever revealed about the game, and the only thing until the E3 Reveal Trailer which feature the Lizard Doggo in addition to other features.

Behavior
The Lizard Doggo will normally run away from players, but if a Paleberry is dropped nearby, the lizard will eat it, and then if the player pets the lizard, as soon as it sticks its tongue out, the lizard will follow the player. While following or if a player can catch up to a fleeing one, the lizard doggo can be patted by pressing the use key (default ). It currently serves no real practical purposes. Although, it can occasionally find a small amount of ore, berries and nuts. It has a single inventory slot you can use if you don't mind making sure its pathing lets it keep up with you.

The following items can sometimes be found in the Lizard Doggo's inventory as time passes (This is not a complete list):

If carrying Uranium or Nuclear Waste, the engineer will receive radiation damage, but the Lizard Doggo won't.

If killed, it will not drop any items.

The Lizard Doggo can forget that it has been tamed (it won't lose the items in its inventory and can be re-tamed).
