La Candace-Cabra

Alright then, let's start tracking us a Chupacabra.

The boys set out to prove the existence of the elusive Chupacabra to the world, but Candace can't stand the wait and first just needs to prove it to Mom. Meanwhile, Doofenshmirtz has the brilliant idea to use his Switch-Place-Inator to remove hair from one person and give it to another so that he can in turn sell his hair growing tonic.

Episode Summary
After Phineas and Ferb cross something off their "bucket list", Buford enters, dressed as Isabella. He asks them, "What'cha doin'?" and Phineas says the real question is to what Buford is doing. Buford says he's dressed like Isabella because he's filling in for her while she's visiting her grandparents in New Mexico. Baljeet adds the dress was his idea.
