Fear Mongerer

The Fear Mongerer is a Shop NPC located in the Village, next to the Bank. They spawn at the location of the Event Stand, replacing it with a giant pumpkin, and they appear for 1 hour before the Spooky Festival starts, stay through the event, and despawn one hour after the event ends. During the hour-long event, one can collect candies to trade with the Fear Mongerer for various items, such as upgraded enchanted books and accessories.

Trivia

 * There was a glitch, when someone was standing on the spot where the Fear Mongerer spawns (not during the spooky event), you were able to access the shop. This was supposedly patched but has been accessed during times other than during the spooky event. This glitch works with an armour stand taken in the Fear Mongerer's place.
 * the Fear Mongerer, is one of the few NPCs that sell pets(not counting the Spirit pet from the Floor 4 boss chest) as well as Sirius, Bea, Diana, and Oringo, selling the an assortment of Zoo pets, the Jellyfish and Turtle pets, the Bee pet, the Black Cat pet, and the Griffin pet respectively.
