Peacock Castle is located in a barren area and is very near to an active volcano.
The castle features several tall spires and a domed roof. It also features a tower over its front entrance with a smaller dome.
Commander ApeTrully and First Squad of Big Green both approached the castle concerning reports of maltreating humans. However, all were mesmerized by Peacock Queen's beauty save for Mystique Sonia who competed with the queen on the castle grounds.
