Sand Worm

Sand Worms '''are long hostile mobs that are 4-7 blocks long, and they spawn in desert, and wasteland biomes. They have 20 making them a decently hard enemy.'''

Appearance
It has a large mouth with small fangs on the inside and four large fangs growing on each side on the corner of the mouth. It has drool drooping from the bottom of it's mouth. It is red or the color of sand. The sand-colored one is more common in deserts while the red is more common in wastelands.

Behavior
It creates 7 block deep tunnels that move throughout the biome. The tunnels are 4-6 blocks wide and it is very common to encounter a sand worm in it's tunnels. The tunnel opening is only 1 block wide. If you are hit you become poisoned and it decreases one heart every 1 real minute. The maximum poison time is 35 minutes and the only way to cure it is by eating a golden apple or swimming in water which isn't uncommon in deserts. It jumps out of it's tunnels up to 25 blocks high and flings sand stacks all around which hurt you. It can be found in groups up to 3 occasionally 4. When dying, it flails around, and eventually explodes flinging sand flying into large sand stacks. It drops sand and worm hide which is mainly used as decoration and is place able on walls, but can be smelted in a furnace with coal and it becomes leather hide.
