Perry The Actorpus

The executive of Totally Tools oversees a contest to find the company’s "spokesanimal" and Perry is crowned the winner. However, the victory puts Perry's secret identity in jeopardy, forcing Major Monogram to appoint Agent S as a temporary replacement. But when Dr. Doofenshmirtz sees his new nemesis is Sergei the Snail, he mistakenly underestimates his new opponent. Meanwhile, Candace has been welcomed into Mandy’s "Stop the Busting" retreat, which aims to teach Candace to control the urge to bust her brothers through positive reinforcement.
