This level, if you couldn’t guess from it’s name, is built on Switchboards. You can use the GamePad to press the direction arrows to help yourself out, but otherwise stepping on the arrow will move you in that direction. Hop aboard the first Switchboard and over to the next island. Hit the ? Block to snag a Fire Flower then climb up to the left for a hidden 1-Up Mushroom before going right.
Defeat the Fizzlit and ride the Switchboard over to a Switch Block so you can continue across. Ahead you can claim a Super Star to take out the enemies ahead and ride the Switchboard to the Switch Block, enabling a path down the mountainside. As you slide down jump off into the alcove with the green pipe. Inside you’ll want to just fall and snag all the coins as you easily reach Green Star #1 .
You’re brought back at the Checkpoint Flag that positions you at a bunch of Switchboards. Make your way across carefully, grabbing the Red Ring and it’s Red Coins (more easily obtained by hitting them on the GamePad) for a Fire Flower . Clear out the Stingbies as you enter the cave then drop down. On this Switchboard, step on the left arrow and duck to reach Green Star #2 cleverly hidden near the waterfall.
Make your way back to the right where you’ll need to time your hits on the Switch Block to thwart the Fuzzlers that rotate around. The Switchboard your on will fall when you hit the Switch Block, just ride it right and jump over the Fuzzler as you go uphill to Green Star #3 . Make your way back left, riding the final Switchboard to the Stamp and the Goal Pole.
You’ll gain access to the Castle and a Toad House for clearing this level.
