I agree with Agent P. Phineas and Ferb and the characters and such are good as they are. They should not be mixed with or in other shows and their characters. In fanfiction is is alright, but not with another television show - Disney or non-Disney. Keep the show "Phineas and Ferb" untouched and as it - to mix it with other shows and thier characters would ruin it.
