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, as 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.

The sandcastle is covered with water. You must fire two eggs from Kazooie's backside inside a bucket called Leaky, which is close to the sandcastle and he will remove the water from the there. then you are able to type words on the floor, by using Beak Buster

Also located inside the Sandcastle is the Black Snippet and the Jiggy it is guarding, both of which are trapped behind a gate in the back of the Sandcastle. The player must spell out "BANJOKAZOOIE" to open the gate and collect the Jiggy (fighting the Black Snippet is optional).

On the Sandcastle floor there's no letter "Q". Grunty asks what's the missing letter in Grunty's Furnace Fun

The table below shows where each letter is located.
