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. Feyersied. 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.
