Bloop

Behavior

Bloop locks towards you and attacks at your location when he starts his animation, meaning you can simply move away with enough movement.

Like other hostile mobs, Bloop will both attack you as well as keep destroying your base until you either :
•kill it
•hit it enough so it leaves you alone
•despawns naturally after a certain number of hits.

Killing the Bloop will give you an achievement as well as rare loot.
