Girl Scouts
Girl Scouts was first appeared in Diary of a Wimpy Kid Old School.
They appeared when a bunch a vans has rolled into the parking lot to be helping out in the Town Park clean up. Each of them organized everyone into separate teams into each one at the clean up.
They have also involved in project like the community garden which the town wanted to build but nobody get their acts together so the Girl Scouts swooped in on a Sunday afternoon.
Not only they helped to organised at the Town Park clean up, they started a fundrasing by selling cookies.
But when Greg is returning to playground, one of the Girl Scouts named Brownie who appeared out of nowhere and totally caught him red handed.
So Billy,Frew and Greg run off and Brownie chasing them with a whistle and the entire Girl Scouts troop was in a hot pursuit. They had the authority to arrest the wrongdoers and they will earn a badge they need.
