The Nitro Creeper is a red creeper added by Natura that is be found in the Nether. Its fuse time is much shorter than a normal creeper's, so be cautious because once you hear it, it's probably too late.
The Nitro Creeper is red with pale-red spots all around its body and its texture seems wool-like. Its face has big golden eyes with a small smile. It will explode immediately with a very short charge-up, unlike a normal creeper that charges the explosion and gives you time to run away. This makes it almost impossible to kill it with any melee weapon. Bows are by far the best.
