Put a tracking device on it, if you die while he is on your shoulder it runs away to a safe location where that is no-one knows lol. Btw if you see Wilson tell him it's safe to come home now... WILSON!!!
Glowtails are one of the four lantern pets. Found in artifact caves, these little guys love Plant Species Z seeds (Heal plants),and your everyday ascerbic mushrooms. It's an easy passive tame. But there are a LOT of bad things in caves you don't wanna get close to, like megalosaurs or arthropleura. Happy taming!
