Mario lands on the grassy starting planet and finds blue Octoombas. The bottom of the planet contains Goombas, Slurples, multiple Item Crystals containing Star Bits, and a single ? Block filled with Star Bits. Meanwhile, a constant comet stream releases Star Bits. Mario should find a twisted pathway to reach a Luma that transforms itself to a series of Pull Stars. Using these Pull Stars, Mario use the Launch Star to visit the pear planet, which is part of a network containing additionally an egg planet and a rock planet. On the pear planet, he can find Goombas, Thorny Flowers, and Item Crystals with Star Bits. One Launch Star takes him to the rock planet while the other Launch Star takes him to the egg planet. If Mario has less than 100 Star Bits when launching himself, ten Star Bits will appear. Once on the rock planet, Mario has to avoid Boulders and find Item Crystals containing Star Bits. A single Sling Star allows Mario to grab three more Star Bits and a single Coin. Mario can use a Launch Star that leads to the egg planet or another Launch Star that returns him to the pear planet. On the egg planet, a Hungry Luma requests Mario to consume 100 Star Bits. The egg planet has a couple of Goombas and more Item Crystals with Star Bits. The Launch Star here takes him to the pear planet while another Launch Star that takes him to the rock planet.

Once the Hungry Luma has eaten 100 Star Bits, it transforms into the tower planet, leaving a pink Launch Star behind and allowing access to the newborn planet. Mario has to climb this tower planet whilst dealing with thorny plants and Goombas. He can also break the Crates by spinning them. After reaching the top of the tower planet, he can use a Launch Star to visit the pill planet. The pill planet's exterior has some Octoombas and many Item Crystals with Star Bits. An empty Item Crystal blocks an opening on the planet, but Mario can destroy it to enter inside the planet. The interior is a circular 2D-side scrolling area with varying gravity. The background color indicates the gravity's direction: a blue background indicates downward gravity while a red background indicates upward gravity. At the top of the planet's interior, Mario finds three Goombas and a Launch Star that takes him to the final planet, the star planet. On the star planet, Mario can collect five blue Star Chips to make five Pull Stars appear. Using these Pull Stars, Mario can finally grab the Power Star, ending the mission.
