Plot[]
Jerry sends the spies to rescue a famous Chihuahua who is the face of a global taco chain. When they get to where he was last seen, they find some bizzare claw marks. Then Jerry sends the spies to protect a pig named Bacon. Unfortunately, Bacon is already kidnapped. The spies find out that an actor in a Chicken Suit named Clucky is behind the kidnappings. Jealous that real animals would replace the men who wear costumes like him, he decides to eliminate them to regain his celebrity status and destroy the company Kooky Farms by putting the animals under mind control.
In the B-Story, Tony's been sneezing a lot more than usual, so he and his siblings try figuring what could be causing it -- after determining that he's not allergic to pollen or whatever's in their breakfast cereal, Tony becomes convinced that he's allergic to Marc. Due to a movie that he had recently seen (where the two lead characters become allergic to each other after spending so much time together), Tony (noting things like how he and Marc share a bedroom and how their school lockers are right next to each other) starts going to extremes in order to avoid Marc as much as possible. But after finishing up the mission and returning home, Tony realizes that he was never allergic to Marc in the first place -- in reality, he's allergic to a new brand of laundry detergent that their mom's been using. But Marc (obviously wanting to get back at Tony), starts avoiding him in the same way that Tony had been doing to him over the course of the episode.
