Where's Pinky?

He's been gone all morning! He didn't even touch his breakfast burrito. What am I going to do?

When Pinky goes missing, Phineas & Ferb create a machine that will amplify Buford’s senses to those of a dog’s. However, it works so well that the animal agents’ secret identities are put in jeopardy. Meanwhile, Candace tries to meet up with Jeremy for lunch at City Hall but gets stuck in a mandatory tour.

Errors

Allusions

 * "And your little dog..." - The line in question that Doofenshmirtz says to Perry and Pinky was lifted from the 1939 MGM classic The Wizard of Oz in which Margaret Hamilton (The Wicked Witch of the West) warns Judy Garland (Dorothy) "I'll get you my pretty...and your little dog, too." This is the second time he says this, the first being the Oz parody Wizard of Odd as Doofen witch warlock.
 * Tron - The password to override the security door, "reindeer flotilla", is Kevin Flynn's password in the 1982 film.
