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 whole level, except for the small hill the player starts on, 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 stars. Yoshi must collect all these stars, because 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 Exclamation Blocks to appear, leading the hero to a red Flatbed Ferry. When Yoshi jumps in this platform, he must quickly press another ! Switch on top of some ! Blocks in his way, while in the platform. Yoshi eventually finds two Spring Balls on top of a couple of ! Blocks. The first one allows Yoshi to reach a very tall row of ! Blocks, while the second Spring Ball alows the hero to collect a Flower, as well as reaching these tall Exclamation Blocks. Yoshi has to press another ! Switch here, and quickly use a red Flatbed Ferry to cross a large pit, but he must be careful, as there is a row of ! Blocks in his way, and the only way to overcome it is by ducking at the right moment. Two Flowers can be collected here if Yoshi jumps over two Piranha Plants in his way. After this, Yoshi finds another ! Switch, which must be pressed to cause a huge row of ! Blocks to appear. The dinosaur must utilize two Spring Balls to jump over two tall lines of Exclamation Blocks. The two last Flowers of the stage can be collected here, both by using the aforementioned Spring Balls. By waiting until all the Exclamation Blocks disappear, Yoshi can find the GOAL! Ring utilizng a red Flatbed Ferry.

Trivia

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