Rock wart

A rock wart is a small venomous hostile mob found on the planet Tatooine.

=Spawning=

Natural generation
Rock warts spawn from spawners in mineshafts on Tatooine at a light level of 0. They are surrounded by mucus in corridors.

=Drops= Upon being killed, a rock wart drops:
 * A 1⁄3 chance of dropping a rock wart eye when killed by a player or hound. The maximum amount of spider eyes is increased by 1 per level of Looting.
 * 5 experience points when killed by a player or hound.

=Behavior= Rock warts have the same behavior as knobby white spiders.

Poison
Rock warts inflict Poison upon attacking. On normal difficulty, the poison lasts for 7 seconds and causes 4 damage. Poison damage is not taken when the player's health is at 1.

Breeding
After killing their target, rock warts lay eggs at the death location. The eggs can be placed on any block in clusters of up to 4, however, they hatch only on sand or red sand. The eggs can be broken without tools and can also be trampled by living entities falling or walking on them. When a multi-egg block is trampled, eggs are broken one at a time. A rock wart can walk on the eggs without breaking them. Harvesting eggs with Silk Touch drops an egg, which the player can collect. Mining an egg with Silk Touch resets the egg's growth.

Rock wart eggs progress toward hatching by cracking. Cracking occurs during random ticks, and an egg hatches once it has cracked 3 times. When a multi-egg block hatches, all eggs within the block hatch simultaneously. Eggs grow faster during the night and typically take 4 to 5 in-game days to hatch.
