Mario must defeat King Kaliente once again to get a Grand Star.


Starting Planet

This spherical dirt ball has been devoured nearly completely by a black hole that somehow reached the planet's core. Goombas and Bill Blasters can be found here.

Lava Reactor

This star-like entity is very large, taking up most of the galaxy. It bears some resemblance to the planet Solar from the Star Fox series. Its northern half holds King Kaliente, while the southern half contains a few sinking platforms that can somehow withstand the lava.
