Minecraft cactus

Ouch! watch out for this prickly pesky block. They are cactuses Cactuses are a block in Minecraft that is found only in hot, hot snow golem repelling desert biomes. Where else? This block can cause half a heart of damage. Just like ones in real life. Cactuses break when you mine the block underneath it so it is tricky to find out how the bottom of it looks. Because of their ability to cause damage, cactuses are useful for mob trapping. Cactuses can be put in furnaces to make cactus green dye for making green wool. That enderman's gotta watch out for that block when he carries it!
