Mini/Minecraft

The minis of Minecraft are mini-creepers.

These blocky green creatures are about half the size of a person, and although they hiss when threatened, they thankfully don't explode. They usually have a name tag above them showing the name that was misspelled.

While Minecraft doesn't have many actual characters, it does have mobs, enchantments, and items, among other things; capitalization of their names can be difficult to master and is a common source for minis. According to the style guide on the Minecraft Wiki, mob and item names should not be capitalized unless they are the first word of a sentence or referred to as a proper noun, but enchantments and status effects have to be capitalized unless used as an adjective. Structure and biome names must be lower-case unless they are the first word of a sentence.

Canon Origin
The creeper is a hostile mob (mobile entity) that sneaks up on unsuspecting players, chasing them and hissing for a second and a half before self-destructing. The creeper was first released in the August 31, 2009 Survival Test update, and is based on a defective pig model that was reskinned, renamed, and given a new function.

Creepers naturally spawn in the Overworld on top of solid blocks with a light level of 7 or less. Creepers drop 0-2 gunpowder, and a music disc if killed by a skeleton arrow.

Because of its habit of sneaking up on players and destroying their stuff, the creeper has become infamous even outside of the Minecraft fandom. Beginning in the Minecraft forums, the hissing sound made by creepers before exploding became an interrupter, where people would type out "ssssSS!" in a conversation to derail it. While the exact origin is unknown, one of the earliest posts of the creeper sound used in this manner dates back to April 11, 2010. The creeper's distinct green pixel face has become the unofficial face of Minecraft, even more popular than the actual face of Notch, the game's creator.
