Castle

The Castle is an area in Supra Mayro Bross - Legend of the Lost Kingdom. It is the final level and the base of Biger Gumba, leader of the Gumbas and a servant of Kupa. The outdoor look of the Castle is unknown, as you are summoned inside the castle with no cutscene.

Supra Mayro Bross - Legend of the Lost Kingdom
The Castle plays an important role in the game. It is the second and final level and the only indoor level in the game, it is also the only level with reachable bottomless pits (The Lost Kingdom actually has bottomless pits, but you cant fall in those ones). Once Mayro reaches the end, he will see a special "Boss" sign. Touching it will move Mayro to Biger Gumba's chamber, and once "defeating" him (Mayro would actually crawl under him), Mayro has saved the Lost Kingdom but can reset his adventure by jumping in a bottomless pit.

Trivia

 * It could be in Supra Mayro 64 as a level after the Lost Kingdom, but this is unconfirmed as the game has not been released, and maybe even cancelled.
 * It is the only level that doesn't have a moving background, however, it could but the background is just deep gray.
 * This level has the most Gumbas out of any stage in the Mayro series, with five in total (six if Biger Gumba is counted)
