RoboCreeper

The RoboCreeper is a extremely dangerous organism, if you could even call it that. It appears to be a variation on the common creeper.

Appearance
The RoboCreeper appears to be made out of a kind of black metal, with bright white eyes. It is around 6 feet high and 2 feet wide, with small 6 inch feet. It's anatomy is unknown, but it is presumed to be like a common creeper's anatomy, but with mechanical substitutes. The reason why no one has ever gotten to examine it is because of it's extreme danger and the fact that it never leaves anything behind when it explodes.

Danger
The robo creeper has 20 hearts of health, making it tough to fight.The RoboCreeper, if encountered and directly faced, does anywhere from 5 to 20 hearts of damage. It has a 0.2 second fuse, getting withing range and exploding. It can destroy ten blocks of obsidian, and vaporize water and lava. It is extremely dangerous, and in addition to that, is extremely smart and often uses group tactics to get near targets and seeks out precious items and buildings and blows them up, with an estimated IQ of 590, compared to normal creepers. If you get near one of them, run as fast as you can and destroy it from far away.
