(Everything on here is only canon in the AU)
[MOSTLY FOCUSES ON THE TROUBLESMAKERS, ALONG WITH THE OTHERS INCLUDED IN THE STORY]
The Troublemakers, along with Squiddy and Shape Bandit, decide to cause some trouble in the middle if the night. Searching for where to go, they discovered a building that hasn't been touched in ages; little do they know that's where things will take a turn for the worst.
