Magma Cube

Magma Cubes are a hostile mob found around The Nether. When killed, they leave smaller versions of themselves, then dying and leaving Experience Orbs. When they move, they jump up and break into many layers momentarily.

Trivia

 * This mob shares many similarities to The Overworld's Slimes. One of these similarities is that they do not burn in lava.
 * Magma Cubes can not jump out of lava if the lava is too deep.
