Occasionally, you will find special creepers in the world that are blue instead of green. These creepers are called Mana Creepers. They are just as dangerous as normal creepers, but in addition, after they explode, they create a Mana Vortex that saps your mana for a while.

Mana creepers drop Vinteum Dust instead of gunpowder when killed.
