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 7:30AM).

Trivia

 * Badger's Hat is a direct reference to Terraria twitch streamer Badger.
 * 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.
