STAGE 26: MAGMA ROAD MARATHON

You'll start in an area with platforms that move when you blow into the mic. Line them up and head forward, collecting coins as you go. You'll reach an intersection with paths going north and west. The first Diamond is near the bottom-left of the screen. Head west, then immediately U-turn left. Follow this path to the summit to grab Diamond #1. From there, drop off to the left, snagging a bunch of coins before returning to the main path.

Keep moving forward. The straight path will end, and you'll need to turn left. Loop around this section a few times to collect all the coins scattered here before continuing north.

Soon, you'll spot Diamond #2 floating right over the hot magma! Remember to blow into the mic to activate the wind platforms and use them to reach the gem. Make sure you grab every last coin in this area before moving on.

Continue heading north. You'll come to another split in the path. Take the left path and enter the cannon. Inside, grab the 1UP mushroom from the leaf in the corner. Now, blow into the mic to move the wind platforms and follow the path to collect all the coins and, most importantly, Diamond #3.

After getting the third diamond, blast back to the main area. Follow the path ahead, collecting coins. Be extra careful when you reach the ring of coins – it requires precise movement. At the very end of this path, you'll find the Star.
