Pixie the Platypus

Pixie is Cassidy's pet platypus who is also a new member of the O.W.C.A.

Early Life
Pixie's platyparents weren't expecting a child, so when Pixie was born, it was a great surprise to them and everyone at the animal shelter she lived in. She was put in a small cage without her parents. Pixie lived a miserable life at the shelter, being under-fed and mistreated. She was ecstatic when Cassidy came to adopt her.

Present Life
Pixie is living happily in Danville with Cassidy. She also goes over to Phineas and Ferb's house to see Perry very often, but he's usually not there. When she can, she follows him to work, where she gets recruited by Major Monogram to be a member of the O.W.C.A. She is currently in training and does not yet have a nemesis.

Personality
Pixie is fierce and a great agent, with a natural instinct to attack anyone she doesn't trust. She usually overreacts to things and gets mad easily, and is sensitive, though she denies it because she thinks being sensitive is for 'wimps'. She is somewhat bossy.

Physical Appearance
Pixie looks like Perry, but Pixie is lavender and has eyelashes. The fur on the top of her head is shaggy and tousled, and up in a mohawk-ish fashion. Pixie's feet, tail, and beak are light pink instead of orange. She has a reddish pink heart clip on her head and a necklace with three bubbles on it, similar to the design of Cassidy's shirt.

Cassidy Parks
Cassidy and Pixie are the best of friends and have a relationship similar to Phineas and Perry's. Cassidy tells Pixie all her secrets, and takes her everywhere. Pixie loves Cassidy to pieces and is never mean to her, and vice versa.

Perry the Platypus
Pixie and Perry are good friends. Perry lets Pixie follow him to the O.W.C.A. and is impressed by her skills. Pixie considers Perry her role model and wants to be an agent just like him. They have no romance-relationship yet, but it's possible they will in the future.

Phineas Flynn
Pixie doesn't interact much with Phineas, but Pixie trusts him because he's Perry's owner. Phineas likes Pixie and likes that Perry has a friend to play with.

Ferb Fletcher
Pixie doesn't completely trust Ferb because he's so quiet. She thinks he's hiding a big secret from everyone. What Ferb thinks about Pixie is unknown.

Candace Flynn
Pixie doesn't trust Candace because she's heard stories from Perry and O.W.C.A that Candace mistreats Perry and doesn't like him. Candace thinks Pixie is adorable and way better than Perry because she's a girl and because of her appearance.

Major Monogram
Pixie thinks Major Monogram is a bit bossy, but otherwise she thinks he's a good boss. Major Monogram is impressed with Pixie and wants to get her a nemesis as soon as he can.
