The Halloween event starts soon, and we will have to find the 9 pumpkins again.
The zone they are in will have the Devils Delight BGM music playing and you'll get a food item from examining the pumpkin.
Report here where the pumpkins are found (zone, location, details if it's hidden well) and item received.
