Sandcastle

The Sandcastle is located in Treasure Trove Cove. It is where all the Cheat Codes in Banjo-Kazooie are entered.

One of the codes for the sandcastle is used to unlock Treasure Trove Cove. However, this makes little sense, since the sandcastle is located within Treasure Trove Cove. Because of this, some players have been led to believe that the Sandcastle was to be originally located in the first world, Mumbo's Mountain, much like the Code Room for Banjo-Tooie was located in the first world, Mayahem Temple.
