The best boy. It is a passive tame and can be picked up. They also provide light.

Their light keeps the baddies away. It's a new mechanic called "charge." Having light with you makes you a good bit safer.

When they find a max level dino they give a few high pitched barks and u get a buff in the bottom Right of your screen warning you.

You need a Glow Puppy! Scary things lurk in the dark and these help keep them away. Passive tame, aquatic mushrooms. Carryable on shoulder. Recommended to be your first tame.

To activate/deactivate the light without removing it from your shoulder, hold 't' on PC and in the emote menu choose 'light.'
