BoomCube is a FireSlime that lives with a family of Creepers in the Desert of Lava. Its father was a FireSlime, but its mother was a Creeper. BoomCube can bounce very high due to the fact that it can detonate a small explosion under itself to launch it on. It can also commit suicide in a massive explosion of lava. It hates the Golden FireSlime for some unknown reason. The hate is mutual.
