Star World 2
Star World 2 is the second Star World level in the game Super Mario World accessible by the Vanilla Dome Star Road. This level takes place under water with large amounts of Rip Van Fish and Blurps. It also features a rare Baby Blue Yoshi.
Star World 2 consists of one underwater area, and a short open screen with the level goal which the Player has 300 seconds on the Timer to complete. The player comes out of the Warp Pipe at the start of the level, next to a Star and a blue Yoshi Egg. As with all Star World levels, there are two ways to complete the level.
 Normal Exit
At the start, the player can either grab the star, or feed it to the Baby Yoshi. If the Baby Yoshi eats the star, the Yoshi will grow up. If Mario or Luigi gets it, they will turn invincible. One strategy is to feed Yoshi the star and then swim up to the top of the level. Once at the top of the level, the player can keep hitting the swim button and bypass all the Enemies. Nothing important is on the bottom, however if the player is invincible, they can get another star by hitting the ? Block. Otherwise the ? Block will contain a Coin instead. Once the player reaches the end of the water area, the player should drop down and enter the Warp Pipe which leads to a Giant Gate.
 Keyhole Exit
The way to get to the Key and Keyhole is almost the same as the way to get to the Goal Post, but instead of entering the Warp Pipe, the player should swim under it and keep going until the keyhole and key are visible. The player should be careful not to swim under the warp pipe too low as that will result in loss of a life. Beating the level this way will allow access to Star World 3. It slightly changes in the Game Boy Advance remake.
