Hidden Star: The Flipswitch Chain

Start the level near the toy-train. You can ride the train or jump onto the railway and use a backflip or triple jump to reach the Launch Star.

Collect Star Bits in a heart shape near pencils during your flight to the next planet.

Gather more Star Bits on the planet that resembles a large metal screw. Look on the bottom side and near the Big Amps where star bit comets land. You need a total of 50 Star Bits.

Feed the Hungry Luma the 50 Star Bits. A new planet will be born.

Use the Star Launcher that appears after feeding the Luma to travel to the new planet.

On this planet, step on the blue flipswitches to turn them yellow. Stepping on them again will turn them back to blue.

Avoid Tox Boxes and spikey moving platforms. Tox Boxes will instantly kill you unless you are inside their mouths.

After flipping all flipswitches on the clear tube planet, jump onto the blue tube and continue flipping the switches along it.

Once all flipswitches are flipped, they will turn green, and a Power Star will spawn on an orange platform off the blue path.

Grab the Star to finish the level.
