Druids are the faceless enemies in red robes that appear in Hypno Tower at Mermaid Cliffs. After its Boss is defeated, a druid can also be found in Mayor Scuttlebutt's abandoned seaside retreat, which is faster to reach because of the nearby warp squid. Kill a druid between 00:00 (Midnight) and 01:00 to earn the achievement. Save the game just before the room with a first druid. Exit the game and set the system time to midnight. Open the game and load the saved game file. Kill the druid.
