Star Hill is a location in Super Mario RPG: Legend of the Seven Stars and Mario & Luigi: Partners in Time for the SNES and Nintendo DS, respectively. Wishes made by characters are sent here, and can be viewed via small stars scattered across the area. Mario and crew can visit the area in hopes of a star piece. The star piece in this level is the only in the game that can be obtained without having to battle a boss.
In Mario & Luigi: Partners in Time, the Commander Shroob will be fought here. It can be accessed by going through the time hole in the basement of Princess Peach's Castle.
