When You Piss Off A Shroob Princess

AU. My first Mario fic. After a Shroob castle party, Elder Princess Shroob needs to rest and her younger sister, Princess Shroob, is determined to keep the peace around the castle by herself. But she didn't expect it to be so difficult. Especially when she gets visits from a few unwanted guests. How long can she handle the job without waking her sister? All characters are OOC.
