Stalker

Stalkers are a hostile mob in Minecraft.

Spawning
Stalkers can spawn in two different ways:

Naturally
About 3-4 stalkers spawn per day in a meteor biome every 30 minutes. They can get out of hand quickly if the player doesn't do anything to stop it.

At night their is a 1% chance of a Stalker spawning 20 blocks away from the player.

Stalkers also have a 5% chance of spawning in a village and which they will instantly attack.

Spawned
The Stalker queen spawns 3-4 Stalkers every thirty minutes.

Behavior
Stakers usually will stay near their queen, protecting her from harm. But sometimes, if their are more then 12 Stalkers spawned up to 6-8 will go on a patrol. Killing any mob for food.

Stalkers are aggresive to passive and netural mobs, attacking them on sight. They also do a biting animation once the mob dies to "eat" the items the creature dropped. Strangely, when Stalkers come in contact with Hostile mobs like Creepers or Zombies, the two will stare at each other, the Stalker makes small chattering noises as if their communicating. Then the two will stop and continue to to whatever they are doing.

Stalkers are known to have incredible jumping skills. So they are able to jump fences. When they come across chickens, cows, sheep, pigs, or horses. They will start to stalk it, sort of like a cat when a player is holding fish. Then attempt to pounce on the prey.

When within 100 blocks of a player, Stalkers can "smell" if the player is holding any raw meat. If the player does have some in their inventory or hot bar. The Stalkers will begin to come towards them. When they get closer to the player, if they player is holding the meat in their main slot, they Stalkers will loll out their tounges. When dropped a Stalker will eat the meat, and suddenly become passive. The other Stalkers though may attack the player once they run out of raw meat. After three minutes the Stalker fed will return back to its normal state.

Staklkers perfer to stay in the dark, so they stay near their biome until night. At that time, Stalkers will turn slightly invisible, but just barely visible for players to see. As their name says they will stalk the player slowly, if the player turns in their direction they willl freeze. Once they are within two blocks of the player they will perform a powerful pounce that instantly kills players They will continue to stalk the player until one of the three happens: The player hits them, they hit the player, or it turns daylight.

At random, two Stalkers near the queen will enter love mode and breed with her.

Abilities
Stalkers are very quiet and have no walking sounds, making it easier for them to follow players

They can also turn invisible.

They can perform an instant kill pounce and bite mobs to death.

They are immune to fall damage and levitation

Stalkers can some times perform a gripping bite, in which they will grab the mob or player and hold onto them, repeatedlly making them take 1.5 hearts until the Stalker or mob/player dies.

Stalkers can also climb walls like a spider and can walk on ceilings.

Drops
Stalker Flesh: A very strong food, when eaten it fills up 6 hunger shanks and gives 10 seconds of regeneration proving it to be very useful.
