text: When you're wearing a Beefalo Hat, Beefalo in heat don't attack you when you go near them. Presumably, they think you're a Beefalo too, or at least no threat.
  Wearing a Spiderhat (a Spider Queen's head) will make Spiders and Spider Warriors follow you and fight for you, even against a Spider Queen. Pigs, even those you've befriended, will see you as an enemy and attack.
  In the Hamlet DLC, Webber generally causes panic among the pig-people due to his monstrous appearance. How does the game make up for this? The Shamlet Mask - a pig's nose, eyebrows, and bushy moustache attached to a pair of glasses. These pigs are more sophisticated than those on the mainland, but apparently not necessarily smarter!
  Similarly, Don't Starve Together has the Clever Disguise, a pair of glasses with a bushy moustache and eyebrows plus a pair of fins, that can only be crafted by Wurt. It has no effect on her, but when given to other characters, it can be worn to make enemy Merms neutral.
  Patchwork Map: There's not much rhyme or reason to the way the world generator stitches biomes together. It's possible for a soggy swamp to suddenly give way to a parched desert, and then to a dense evergreen forest.
