Drum Castle

Drum Castle (ドラム城, Doramu-jō) is a huge castle located on top of the largest mountain of the Drum Rockies on Drum Island. Formerly inhabited by the royal family and their servants, the castle is now owned by dr. Kureha. Since Wapol left, the main entrance been left open (because snow birds made a nest on top of the door), causing many rooms to freeze over. The armory contains many strong weapons, and in one of the towers is a powerful cannon, which no longer works properly, since birds also made a nest there, as well.

First appearance: chapter 132; episode 79.
