Castle

"Some monsters occupy multiple beds. When you need more beds, upgrade the castle." The Castle is a Structure that allows for Monsters to be placed on an Island - each castle provides a certain number of beds for monsters. Aside from Gold Island, each island starts with the same Basic Castle and the progression through the castles is the same, with the same number of beds for each level of castle (the number of beds per castle is increased on Ethereal Island, due to the fact that Ethereal Monsters occupy large numbers of beds), but the time and cost required and Experience granted for each upgrade differs based on the island. Gold Island has a single castle - the Crystal Castle - does not have a bed limit, and cannot be upgraded.

There are two mini-games that you can play from the Castle; you can learn more about them by clicking on the links below: The Castle produces a bass sound. However, it cannot be heard until you have at least a Modest Castle.

 * When first introduced, the Extravagant Castle had a maximum of 52 beds. However with the update to version 1.1.3, the maximum beds was increased to 60.
 * The castle on Shugabush Island does not produce any bass sound. Instead, Shugabass produce a bass sound.


 * For a long time, there was a hint of a new castle being added. The hint could be viewed from the log-on screen hints and tips. It said, "The Extravagant Castle is the Maximum Castle. For now."  This hint has now been realized in the Paradise Castle.
