World 3-5 (New Super Mario Bros. Wii)

World 3-5 is the fifth level of the third world in New Super Mario Bros. Wii. This is a vertical level, and will only autoscroll when all players step on the rotating pink block. There are Propeller Blocks all over the level, red and green Koopa Troopas, ice blocks, Fire Piranha Plants and red blocks which are only seen after activating the ! Switch in the World Map. Completing this level will unlock the ! Switch, that will allow to proceed to the world's castle.

Star Coins
The first Star Coin is always available, while the second and third ones are only available while the ! Switch is activated.
 * Star Coin 1: The first Star Coin is floating to the far right of the first Green Pipe-emerging Fire Piranha Plant. Mario and co. can obtain it with a Propeller Suit/Block, or by jumping at just the right time so as to avoid falling.
 * Star Coin 2: Instead of taking the usual Green exit Pipe at the end of the level, Mario and co. should jump up from the mushroom block to the red block platform (after having pressed the ! Switch outside the level), then up to the Red Pipe. Once there, the second Star Coin is on top of many Ice Blocks, guarded by a Red Koopa Troopa.
 * Star Coin 3: Not too far up from the second Star Coin, the third Star Coin is floating in midair, guarded by four Paratroopas. Mario and co. should jump to the Star Coin while the Paratroopas are far away.

Secret Exit
At the top of the first area, there is a red pipe beside the green exit pipe. This red pipe is only accessible after activating the ! Switch in the World Map. This exit unlocks a yellow Toad House. This exit, along with the normal exit, is required in order to advance through the game, unless the player uses a Cannon.
