From the Super Mario Wiki
This article is about the bonus world. For information about the roads that lead to this world in Super Mario World
, see Star Road
The Star World is an extra-dimensional area in Super Mario World that can be reached by one of the five Star Roads.
The levels have different colored Yoshis in them, and there's a Yoshi in the beginning of a few of the levels so the player can exit the stage with a new ride. From the Star World, one can also get to the Special Zone.
To beat the Star World, the player needs to find the secret exit first, and then the normal exit. Through finding Star Roads and clearing stages in the Star World, the player can take shortcuts in completing the game.
The Star Roads link to Donut Plains, the Vanilla Dome, the Twin Bridges, the Forest of Illusion, and the Valley of Bowser.

Appearances in other media
The Star World appeared in at least two episodes of the Super Mario World animated series, although here it was referred to as the Star Path.
The Star Path first appeared in the episode "Send in the Clown" where it was used by Mario, Luigi, Yoshi and Princess Toadstool to transport themselves to Neon Castle. In "King Scoopa Koopa", the Star Path is used by Mario and Princess Toadstool to escape from several cave-people (as well as from Luigi and Yoshi), who have been mutated into Chickadactyl-monsters.
- In Super Mario RPG: Legend of the Seven Stars, the Star Road would appear to have become identical to the Star World, being a large star floating over clouds and even featuring the Moon in the same position seen on Super Mario World's Star World. As a matter of fact, it is possible that the Super Mario RPG Star Road actually was a misnamed form of the Star World.
- The secret World 9 of New Super Mario Bros. Wii is similar in appearance to the Star World.
- Superstar Road in New Super Mario Bros. U is also a throwback to Star World. Not only is it star-shaped in appearance, but it is accessed from the main overworld through a star-shaped portal similar to a Star Road.
- The demonstration galaxy for Super Mario Galaxy shown in a demo at E3 2006 was also called Star World.
