Sheepuffs are the Aether's sheep. They randomly puff up and jump very high, sometimes landing on islands or gold dungeons. If they stand in one spot for long enough, they strip the Aether Grass and turn it into Aether Dirt. If sheared, they cannot jump very high until they eat enough grass to grow their wool back. They give much more wool when sheared than regular sheep. A sheep spawner placed in the Aether will spawn Sheepuffs. Also, Sheepuffs spawn with different natural colors, including purple, lime green, and cyan.
