User blog comment:Kuzlalala/Lala's Long but Orderly Put Theory about Phineas and Candace's Biological Father/@comment-970465-20110805134806/@comment-753210-20110805144630

I know, it's a strange world after all. Besides:

1. Candace was in Perry's bodies, with her hormones and stuff. 2. Maybe that's why Phineas thought that platypi don't do much. 3. Maybe his poisonous spurs were removed or that "domestic platypi" aren't poisonous. 4. According to "Oh, There You Are, Perry", there are many platypi in Danville. 5. Perry's a domestic platypi, and maybe, because he used to be a human, he's more used to be at a human house than a river. 6. It was only one sentence that should not be taken seriously.

Lastly, yes, it's not much proof that he used to be a human. There are other proof, and you should check them.
