On your way through the Mushroom Universe, you will travel through 8 Main Galaxies from within smaller galaxies/planets nest.
Your first World, the world you start off in, is called: Home Galaxy. This galaxy, from the TPSG-scope, resembles that of the first 4 inner planets of our solar system albeit a bit more hostile. This Galaxy is home to 5 light and loose planets/smaller galaxies.
Your second World is called Neighbor Galaxy (Neighboring Galaxy). This galaxy, from the TPSG-scope, resembles that of the Asteroid belt from our solar system albeit more colorful and happy looking. This Galaxy is home to 5 very light and zesty planets/smaller galaxies.
Your third World is called The Outer Galaxy (Out There Galaxy). This galaxy resembles that of the outer gas giants of our solar system, albeit less gasseous and heavier planets. It is also the Galaxy that is known for 5 lost and paranormal planets.
The fourth World is called Mushroom Way. This galaxy mimics that of the Milky Way. Being very large for a galaxy, this only holds 5 steady and mysterious planets. The rest are all too hot or too cold to support any type of life. It could take a while to get from one galaxy to another as the paths of each galaxy are constantly changing on the TPSG-scope, unlike the other Worlds.
The fifth World is called Far Out Galaxy, known for it's extraneous and very wild and festive inner galaxies. Also, it has the farthest range from it's preceeding galaxy. Unlike the other World's galaxies, Far Out's has the most disarray variety, ranging from Mechanical to Flower to Lava.
The sixth World is called Stardusted Galaxy (The Star Galaxy). It is the gentle giant of all of the galaxies. It reigns the title "Prettiest Galaxy", with its stardusted paths and beautiful constellations. It is home to 5 of the gentle giant planet/galaxies.
The seventh World is called Galaxy 52. It was given this named by Mushtologers because no one knows what lurks in the depths of the dark and sparkly Galaxy. Thus the ominous name Galaxy 52 was assigned to it until people knew what dwelled inside of the swirling cloud of stars and rocks. Some people say it contains 250 planets, others say it has none, but it's those people who say that they feel an ominous evil power emitting from the Aura of the distant star in the sky that makes this Galaxy so eerie.
The eighth and final World in the game is called The Edge Of The Universe. No mushroom person or bean person or any person for that matter knows how large the Universe is. But when you come to the Edge of it you'll actually realize how small the Universe really is. This is where Bowser Koopa resides seeking for something, keeping the player busy by doing useless and senseless tasks, just to keep them occupied. But what could possibly sustain and the End of Eternity?
The Special Galaxy (The ninth World), shhhhh.....it's a secret.
