Adyson Sweetwater is one of the Fireside Girls in Danville Troop 46231.


She, Isabella, Gretchen, and Milly were the backup singers for Phineas and the Ferb-Tones as the Ferbettes ("Flop Starz", "Phineas and Ferb Musical Cliptastic Countdown").

She was a back-up singer with Gretchen in the song "S'Winter" ("S'Winter").

Immediately following Phineas and Ferb's treehouse fight with Candace and Stacy, as all the Fireside Girls are cheering. Adyson's mouth moves along with the line "Way to go!" ("Tree to Get Ready"). She was also one of the guitarists with Katie in the new version of "Flying Fishmonger" ("The Flying Fishmonger").

When Phineas and Ferb built an Animal translator, she and Milly were explaining television to Isabella's dog, Pinky, unsuccessfully ("Interview With a Platypus").

Adyson, along with the other Fireside Girls, knows about Isabella's wish to marry Phineas ("That Sinking Feeling").

Adyson is known for her spontaneous and quick-thinking. When Phineas and Ferb travel around the world, Adyson took Isabella's place as troop leader after Isabella leaves with Phineas and Ferb. She ordered the other members and Clay Aiken to help get the party ready ("Phineas and Ferb: Summer Belongs to You!").

When Phineas and Ferb build a bio-dome, she is shown to be accident-prone, getting heatstroke, being swept away by a current, having a rock fall on her head, and falling on a rock while climbing a mountain ("The Great Indoors").

Physical Appearance

Adyson has straight dark brown hair with large bangs and a curve at the bottom. She has green eyes, rosy pink skin, and a red headband (which she sometimes doesn't wear). She wears a sleeveless uniform with a split in the collar and sides at the bottom, and high-top shoes.

Known Patches


Isabella Garcia-Shapiro

Adyson is good friends with Isabella. She sang with Isabella in the song S'Winter, along with Gretchen. She willingly took Isabella's place as the one in charge when she left with Phineas and Ferb to circumnavigate the world and helped her up on the plane when Clay Aiken sang ("Phineas and Ferb: Summer Belongs to You!"). In "Isabella and the Temple of Sap", Isabella seems to get annoyed with her because she mocked her by made up her "Help Thy Neighbor" patch and instead renamed it as "Let's Help Phineas and Ferb" patch. She and the other Fireside Girls also participate on romantic cruise ship, which they know it's Isabella's opportunity to have romantic times with Phineas.

Later that summer, she got saved by Isabella when she was caught in a river and forced downstream. Also, Isabella helped her heal from her concussion ("The Great Indoors"). Then, as Adyson said that they already spread out fliers, Isabella got annoyed.

In "Act Your Age", Adyson initiates the Fireside Girls' plan to bring back Isabella and Phineas together. Although the plan didn't work out, they eventually reunited and she stated that the time would tell for themselves to be together.

The Other Fireside Girls

During the search for the maracanut tree, Adyson got tethered to Gretchen as the latter was reading a book and calling out directions to the other girls ("Isabella and the Temple of Sap"). She, along with the other Fireside Girls, sometimes complain about earning accomplished patches more than once ("The Remains of the Platypus"), due to their frequent participation on Phineas and Ferb's projects.

In "Act Your Age", she plays a larger role in the episode as she seems to have become the leader of the group during her teenage years. As she is pretty understand about relationships, she explained to Ginger and the other girls about the art of manipulation. Later on, after the girls reminisced about Phineas and Isabella's unrequited love story, she initiated and organized their plan to make a romantic dinner for Phineas and Isabella, along with Ferb, Baljeet, and Buford.

Phineas and Ferb

Along with the other Fireside Girls, Adyson is often involved with Phineas and Ferb's Big Ideas. Notably, she sang together with Isabella and other Fireside Girls as "The Ferbettes" ("Flop Starz", "Phineas and Ferb Musical Cliptastic Countdown") with Phineas and Ferb. She also helps Phineas and Ferb to spread out fliers to promote Phineas and Ferb's projects ("The Lemonade Stand", "The Remains of the Platypus"). She also helps setting up Isabella's birthday party ("Happy Birthday, Isabella").
