The group on Phineas and Ferb which is similar to Campfire USA and Girl Scouts is called "The Fireside Girls" or "The Loyal Sisterhood of the Fireside Girls".
The group name from the cartoon Phineas and Ferb is Fireside Girls, also known as The Loyal Sisterhood of the Fireside Girls. They are an analog, and parody in some ways, of the Girl Scouts or the Campfire Girls.
