Birabuto Kingdom is the first level on Super Mario Land. Set in Sarasa Land, it is a standard level with platforms and enemies.
There are three parts to this world, all of which are similar, except the Easton theme plays during World 1-3.
Enemies found here are Chibibos, Nokobons, Kumos, Flies, Bunbuns, Pakkun Flowers, and Gaos.
At the end of World 1-3, Mario must fight King Totomesu, a giant Gao, and defeat him. In the room after him is a fake Princess Daisy, really a common enemy in disguise, which runs off.
