this is a very cute and good tame slobery fish dog with a face only its mother could love. but it can light up. useful for reaper queen impregnation due to light up.
So no one mentions this for Console,To turn Any glow creatures light on when on your shoulder you need to go to emotes and (wait for it) Clap,you clap so it turns on the lights
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.
