In this mission, Mario must use the Spin Drill to dig and drill through dirt to get to the next destined area. Mario eventually has to fight Digga-Leg. He has to drill through the planet to hit Digga-Leg's underside. After three hits, Digga-Leg explodes and Mario gets a Power Star.
Silver Stars Down Deep
Using the Spin Drill once again, Mario must use the drill near the end to find five Silver Stars which in the end combine in one to become a Power Star. After this, the Spin Drill is put in the Engine Room of Starship Mario.

- The backbeat of the music in this galaxy sounds slightly similar to the music that plays when Mario collects a Fire Flower or Ice Flower.
- The entire galaxy is contained inside what appears to be an enormous, rocky sphere with giant holes in it, the appearance of which is similar to the large sun in Bowser's Galaxy Reactor as well as the Melty Molten Galaxy which was contained in a massive core.
- The galaxy's name is a pun on "shindig".
- It is possible that since Digga-Leg very much resembles Megaleg from the first game's Bowser Jr.'s Robot Reactor, that the name of the level "Digga-Leg's Planet" could be compared to the level name "Megaleg's Moon".
