Ghost Castle

The Ghost Castle is actually the back-right tower of Bowser's Castle on Yoshi's Island. It is infested with many Boos, including rare ones such as Boo Man Bluffs, Boo Buddy Blocks, and others. Many chambers are dark and eerie, and some are even cavernous!

The Ghost Castle is only referenced in Yoshi's Story, in which it is Stage 6-3: Ghost Castle.
