Some fans believe that Perry the Platypus is Phineas and Candace's biological father. This was first brought up by Bobtherandomguy in one of his posts, which was then developed by various theorists including Lala Stellune and NotAGothChick101. In Bobtherandomguy's theory, Perry got injured and had his soul transplanted into a platypus. Lala Stellune said that Perry turned into a platypus in purpose after a major conflict with Linda Flynn.
