Sneezeshrooms

Sneezeshrooms would spawn in the dappled forest, look like autumn sneezeweed, and have multiple uses such as:

• Creating quickly-fading puffs of spores and a redstone signal when hit or stepped on, hiding mobs within them
• Making potions without nether wart that mimics the spore’s effect at a bigger scale (like smokebombs)
• Spreading explosions from tnt (not creepers) to where its spore particles are
• Expanding the range of splash & lingering potions
• Being used in mushroom soup to cause temporary nausea and blindness but also restore health quickly
• Repelling creepers (Creepers are afraid that if they breathe in sneezeshrooms, they’ll explode from sneezing)

For building, players can prevent sneezeshrooms from making spores by placing water under the block they’re attached to.
