Neutral Mobs

Neutral mobs only attack if provoked.

Ghost

Spooky. Like any undead, they spawn in the dark and burn in the sun.
Ghosts actively avoid bright areas and will vanish if exposed to light for too long. They sometimes drop spectral wrappings when killed, which can be used to brew invisibility potions or craft possessed pumpkins.

Watcher

A strange creature found only in the End dimension. They hover in the air silently, tracking the player's every move. They do not have much health, but one should avoid being on their bad side when bridging across the endless abyss (they shoot lasers).

Grizzly Bear

Found in taigas & redwoods. Behaves exactly like polar bears.
