Sarasaland

Sarasaland (referred to specifically as Sarasa Land in modern games) is a region of the Mushroom World, and the setting for Super Mario Land. The realm itself is ruled by Princess Daisy and is made up of four kingdoms: the oceanic Muda, the Eastern Island-based Easton, the ancient Egyptian-styled Birabuto, and the ancient China-based Chai.

Super Mario Land
Sarasaland was once taken over by the purple alien Tatanga, who, under the orders of Wario, captured Princess Daisy and brainwashed Sarasaland's inhabitants. Fortunately, Mario arrived to conquer the invader inhabitants and rescue Daisy.

Although Sarasaland hasn't actually made an actual appearance in many years, it is often mentioned in Daisy's official bios in various spinoffs and sports games.

It is believed that Daisy Circuit took place in Sarasaland in Mario Kart Wii. However, this is unconfirmed.
