Shroob Castle

Shroob Castle was the Shroobified version of Princess Peach's Castle, after the fortress was taken over by the extraterrestrial Shroobs. The dark castle is the setting of final chapter in Mario & Luigi: Partners in Time. Quite the Contrary, the Save Album recognizes as Peach's Castle of the Past regardless of Princess Shroob's control and the appearance of the castle.

Appearance
The castle towers were changed into tall purple mushrooms, along with all the pillars and bushes. The castle itself glowed slightly green (but mostly purple), completely Shroobified to fit the personality of Princess Shroob. Inside, a lot of the castle seems the same as the original in an odd way, though everything is more violet and dark. Glowing purple mushrooms grow all around the castle.

At the beginning of the castle is the massive Princess Shroob statue where the Mario Bros. fought Princess Shroob, which of course, was never in the original castle.
