Fireside Girls

The Fireside Girls are a girls organization seen in Phineas and Ferb, similar to Camp Fire USA and the Girl Scouts. The only known troop in Danville is Troop 46231. The girls' names are, from left to right: Katie, Adyson Sweetwater, Holly, Gretchen, Ginger, and Milly. This troop appears to be led (at least partially) by Isabella Garcia-Shapiro, while the organization appears to be led (and founded) by Eliza M. Fireside. Its founding time is unknown, but it can be assumed it is relatively recently due to Eliza still being alive. It is unknown if there are additional troops in Danville, or elsewhere.

The girls show a large variety of skills, and often use these to help Phineas and Ferb with their Big Ideas. They also use their handbook, which contains information on a large variety of subjects - such as Time Travel and Car Engines. Most of the activities or information listed within the guidebook are often linked to patches, and most of these patches allow them to help Phineas and Ferb in one of their many projects.

Accomplishment patches
Throughout the show, Isabella and the Fireside Girls are earning patches. Usually they are conveniently linked to whatever Phineas and Ferb are doing for the day, while others are just mentioned. Though the patches are usually just glanced over, the girls in Isabella's troop are all extremely enthusiastic about earning patches, and their sashes are usually shown full of patches.

It should also be noted that even if a troop member has already earned a patch, they can still get more by doing the same task again. In "Isabella and the Temple of Sap", regarding the 'Help Thy Neighbor Patch', Ginger had 52 of them and Milly has 53 (because she 'went back that one afternoon').
