Creeper

For those of you who aren’t familiar with Minecraft, it’s a PC game (also available on Xbox 360 and some mobile devices). To quote the game’s website:

Minecraft is a game about placing blocks to build anything you can imagine. At night monsters come out, make sure to build a shelter before that happens.

The Creeper is a hostile mob that will ambush players and explode, causing damage to the player and the surrounding blocks and mobs.

Creepers spawn in the overworld at night and in locations with a light level of 7 or less. They are especially dangerous as they are almost completely silent (except for footsteps and their hissing noises when ready to explode), and their explosion is devastating at short range.

The Creeper has gained considerable notoriety among Minecraft players for their infuriating habit of sneaking up on the player and killing/hurting them and/or damaging structures.
