Exploding Creeper - (Minecraft)

After creating a working TNT block, I wanted to take on the challenge of making a Minecraft Creeper that could actually explode.

Just insert the Flint and Steel into the articulated head and watch the creeper blow apart. While designing this, I also wanted it to be compatible with the Minecart that I had built to go with the TNT block. All the related designs are shown below.

Caution: Depending on the strength of the elastic, parts of this model can and will go flying in all directions.
