From left to right: Milly, Katie, Ginger, Gretchen, Holly and Adyson

The Fireside Girls Troop 46231 is a troop of girls from Danville USA and are recurring characters in The FT Squad's Adventures With Phineas and Ferb.  Led by Isabella Garcia Shapiro, they often do activities to obtain patches, using their different skills and techniques.  They often help Phineas and Ferb with their projects, though this means they have a lot of "Help Thy Neighbor" patches as Isabella calls them. 

While the troop is a girls organization, it has a boy member who's also the manager who keeps track of the patches and activities the troop has done.  This is Kyle Larman.  He joined the troop after winning a contest in Reno Nevada before summer started, but he is very shy and easy to scare.  The girls enjoy his company and never tease him about his behavior.  They always encourage him to have fun with them and will help out when necessary.
