Hit That Switch!!

Hit That Switch!! is the second extra level in Super Mario World 2: Yoshi's Island and its remake Yoshi's Island: Super Mario Advance 3. The majority of the level revolves mainly around the use of ! Switches. All the Red Coins in this level are found in plain sight.

Gameplay
Yoshi begins the level near a Warp Pipe to the left, which takes him to an area where he can find two Winged Clouds and two Crates, all containing a total of 20 stars. Yoshi must collect all of these stars; as the player will not have any other chance to get stars since they don't appear anywhere else in the level. Yoshi encounters the first ! Switch ahead of this pipe, and he needs to press it to cause several ! Blocks to appear, leading him to a red Flatbed Ferry.

When Yoshi jumps on this platform, he must quickly press another ! Switch on top of some ! Blocks in his way. Yoshi eventually finds two Spring Balls on top of a couple of ! Blocks; The first Spring Ball allows Yoshi to reach a very tall row of ! Blocks, while the second allows the hero to collect a Flower, as well as reaching over the ! Blocks. Yoshi has to press another ! Switch here, and quickly use a red Flatbed Ferry to cross a large pit, avoiding a low-clearance row of ! Blocks by ducking at the right moment. Two Flowers are found on this path, each above two Piranha Plants.

After this, Yoshi finds another ! Switch, which when pressed causes a huge row of ! Blocks to appear. The dinosaur must utilize two Spring Balls to jump over two tall lines of ! Blocks. The two last Flowers of the stage can be collected here, both by using the aforementioned Spring Balls. By waiting until all the ! Blocks disappear, Yoshi can find the goal roulette utilizing a red Flatbed Ferry.

Trivia

 * This level's concept of dashing to the exit by relying on block-producing switches was reused for the levels Run for It in New Super Mario Bros. U and P Switch Peril in New Super Luigi U.
