Creeper

The Creeper is a dangerous monster from the game Minecraft. They will famously attempt to attack players by self-destructing.

Description:
Creepers are lime-green and white monsters, about the height of a human, with a sad face consisting of two wide eyes and a large mouth fixated in a permanent frown. It has no arms and four legs, two on the front side of its body and two on the back.

It was determined by Game Theory that the Creeper is actually some sort of sentient moss, specifically peat moss, which explodes to spread its spores via the body of its victim.

For unknown reasons, Creepers are afraid of felines, and will flee if they see one.

Abilities:

 * Can cause its body to self-destruct, exploding with enough force to kill a nearby human and create craters.
 * Can absorb electricity from sources such as lightning and utilize the electricity to boost its explosive power.
 * Is capable of utilizing bodily ailments such as poison or Magically induced effects such as slowness when exploding, spreading that effect to those hit by the explosion.
 * Despite the lack of arms, Creepers are capable of climbing vines and ladders, however they are not very intelligent and will rarely utilize this ability knowingly.

Trivia:

 * The Creeper was created on accident during an attempt to create a pig.
