Shroob Castle

Shroob Castle is the corrupted version of Peach's Castle set in the past after it was taken over by the Shroobs. It is the setting of the final chapter in Mario & Luigi: Partners in Time. The Save Album refers to it as Peach's Castle (Past), despite the fact that Princess Shroob has complete control over it.

Appearance
The castle towers are changed into tall purple mushrooms, along with all the pillars and bushes. The castle itself glows purple. Inside, a lot of the castle seems the same as the original, only darker, with the Shroob emblem and more violet in coloration. The map resembles the one of the future castle. Glowing purple mushrooms grow all over and a giant statue of the castle's ruler, Princess Shroob, can also be found here. Shroob UFOs fly around the exterior of the castle. Beneath the castle is an underground cellar, and unlike the Shroob castle, it has the same music from the cellars in the original castle. It has a few enemies, most of them being Shroobsworth, Shroob Rex and Soul Bubbles. A regular Chain Chomp pesters Mario, Luigi, Baby Mario and Baby Luigi here as well.
