-Hostile

-The first ever hostile mob which is totally fantasy that we have encountered, i think

-Can be found in Deserts, Badlands, and Soul Sand Valleys

-Has three variants depending on the biome its in

-Shoots sand as a short ranged attack when you're far from it

-Carries, spins, and flings around entities (including you) and dropped items if it gets near

-Takes damage in water

-Projectiles do little damage to it

-Drops Guster Eye

-Guster eye can be used to create a Pocket of Sand which shoots sand, and consumes Sand in your inventory as ammo (Yes this is a joke item)

-Guster eye can also be used to create Gustmakers

-Gustmakers will create Sandy tornadoes in a straight line that will carry dropped items and entities like Gusters

-Can be used as Defence, Contraption, Or transportation

-Try naming a Guster "Tweester"
