Restless Creeper

Note that this does not exist in Minecraft; it was written purely as a fiction article.

Restless Creepers are clever variations that are famous for the mass destruction they are known to cause. They are twice as big as a normal creeper and are usually followed by Conducive Creepers. They make noises similar to an Enderman's death sound.

Tactics
Restless Creepers can spit out fireballs that leave behind a huge crater, and can break through tough materials like Bedrock and Obsidian. Even when killed, they are likely to return and have a habit of coming back after defeated and are hard to get rid of. Their fireballs cannot be deflected and can kill low-health mobs in one hit. When in a melee range, they can freeze the player in place and set them on fire. The flames, however, are green-blue and deal damage 1.5x faster and cannot be put out with water.

Habitat
A good way to avoid having to deal with Restless Creepers is to keep your buildings well-lit and protected by Cobblestone, as it is the only material that cannot be blow up by their fireballs. They are most commonly found deep underground.
