The Creeper is a creature with a curious block-like appearance that lives in a hidden cave in the Caustic Caverns. Creepers are generally silent, and prefer to draw in close before self-detonating. They are tall and blocky in appearance, with bright green and gray pixel skin.
Several Creepers can be found in a mine shaft in the north-west section of Caustic Caverns across a mine cart bridge. The entrance is marked with large squarish boulders and covered with breakable blocks that strongly resemble Minecraft dirt and smooth stone. After tunneling a short distance, the tunnel opens into a small cave where several Creepers emerge from the dark tunnels one by one. Finally, the last creeper to appear is the Badass Creeper.
The Badass Creeper is a unique variant of the regular Creeper. He is much larger and produces a bigger explosion when killed. The first creeper encountered may be a Badass Creeper. The last Creeper encountered will always be a Badass.
Creepers will chase after any character they see that gets close. When in close proximity, a Creeper will produce a sound similar to lighting a fuse and violently explode. Shooting a creeper while the "fuse" is going will prematurely trigger the explosion away from the character. Creepers have no form of attack other than this suicidal explosion.
- Phaselocking a Creeper about to explode may cause the game to crash.
- Badass Creepers have a chance of dropping the Longbow or Blockhead. Creepers commonly drop Minecraft themed skins for each character class. Badass Creepers always drop a Minecraft themed head for each character class.
