A Trousle of Bones
A gang of skeletons robbing your neighborhood (can also be used for a bunch of old papers getting into a fight in the hallway)
A trouple of bones robbed my house. They took my video game and my lunch money.
The trouple of bones were fighting in the hallway. It was like a paper war.
I saw a trouple of bones walking down the street. They looked like they were planning something bad.
