Badger's Hat

Badger's Hat is a vanity item dropped by the Eye of Cthulhu or the Wall of Flesh when they are both defeated in the same day (7:30PM to 7:30PM Next day).

Trivia

 * Badger's Hat is a direct reference to Terraria Twitch streamer Badger. The fact that you have to defeat the Eye of Cthulhu and Wall of Flesh in the same day to obtain it refers to his speedrun playthroughs.
 * The tooltip is in reference to how the green part of Badger's iconic hat is invisible during his streams.
 * The in-game hat will sometimes have the green part of it turning invisible at random times.
 * Equipping the hat in the armor slot, and the vanity slot at the same time, will stack them, creating a longer hat.
