Star Shrine

The Star Shrine (called the Star Temple in the Player's Guide ) is an area accessed from the top of the past version of Star Hill, as seen in Mario & Luigi: Partners in Time. Mario, Luigi, Baby Mario, and Baby Luigi come here looking for the last two Cobalt Star Shards. The area consists of many star-shaped and colorful platforms floating in space. A living, star-shaped gate also resides here. The sky above the Star Shrine is gray in the map of the past Mushroom Kingdom but darkish blue in the map of the present Mushroom Kingdom.

The Elder Shrooboid, the boss of this area, turns Toadbert and Kylie Koopa into Shroob mushrooms here. Mario and company defeat the Elder Shrooboid and get the last two Cobalt Star Shards here.

Paper Mario's Star Haven is very similar to the Star Shrine in appearance, and is also reached by ascending Star Hill (or "Shooting Star Summit").
