Pumpkin Moon

The  is an event added in the 1.2.1 Halloween update and summoned with the Pumpkin Moon Medallion at night. The visual indicator is the moon turning orange (as seen to the right) with a spooky jack-o-lantern face on it. The moon stays in the same phase (waning, waxing, full, and everything in between) as the normal moon would be, but uses the new texture. The music that plays in this event is also used by the Solar Eclipse event.

The Event
There are up to 15 waves in the Pumpkin Moon, and waves progress as you kill Pumpkin Moon Enemies. The bosses will drop items more frequently if they are killed during later waves. On wave 15, the Mourning Wood and the Pumpking are both guaranteed to drop their respective Trophies. Each Pumpkin Moon enemy increases the wave's score by a differing amount when killed. After a wave's score is met the next wave begins, and the wave score is reset to 0.

If the event is not completed by sunrise (4:30AM) the event will simply end.

Scores required for each wave:
 * Wave 2: 25
 * Wave 3: 40
 * Wave 4: 50
 * Wave 5: 80
 * Wave 6: 100
 * Wave 7: 160
 * Wave 8: 180
 * Wave 9: 200
 * Wave 10: 250
 * Wave 11: 300
 * Wave 12: 375
 * Wave 13: 450
 * Wave 14: 525
 * Wave 15: 675

Scores for Defeating Enemies

 * Scarecrow: 1
 * Splinterling: 2
 * Hellhound: 4
 * Poltergeist: 8
 * Headless Horseman: 25
 * Mourning Wood: 75
 * Pumpking: 150

Creating an Arena
One of the best ways to get to wave 15 is to create an arena with several traps to deal with the smaller enemies while you focus on the pumking, such as the one detailed in the video below.
