The Truffle Sniffer is a pig boss that is infested with mushrooms. I got its name inspiration from the fact that pigs are often used to sniff out these fungi called truffles, which are used in food. He attacks by spreading spores everywhere, dashing at the player, shooting spore clouds at the player, and pulling a clump of fungi out of the ground and throwing it at the player. It is intended to be fought in mid pre hardmode, inbetween the EoW/BoC and the Queen Bee. It can be summoned using the Suspicious looking Truffle while in a mushroom biome. It drops Truffle Dishes, which give Exquisitely Stuffed for 8 minutes, a bunch of glowing mushrooms, the Mushblade, which shoots mushroom projectiles, and the Spore Staff, which shoots fast moving fungi spores. In expert mode, it will drop the Deadly Truffle, which spawns stationery spores around the player that damage enemies. So basically its a pre hardmode spore sac.
