The pilot begins with the Cockroaches inside a fridge where they soon hide once Oggy opens it. Oggy notices the roaches, who are bathing inside his yogurt. This prompts the Cockroaches to attack and run away from Oggy while stealing some of his food. During their chase, Joey drops an apple, causing Oggy to trip and fall an entire flight of stairs. The roaches then decide to hide in a washing machine and Oggy begins to speed up towards the machine. However, Joey closes the lid, causing Oggy's head to be squished on impact.
Later, Oggy (who's now holding a cooked chicken) is placing several mouse traps around his fridge in hopes of stopping the roaches. He then sits down to watch television only to realize that Marky has been inside the chicken all along and has run away with it. Marky runs to the top of a staircase where Oggy gets the idea to pull the stair runner under the chicken and roll it back towards him. However, Marky has secretly put a stick of dynamite inside. causing it to explode right in Oggy's face.
During another raid, the roaches run up a wall and onto the ceiling with Oggy giving chase. On the ceiling, Oggy faces the Cockroaches but Joey smugly points down at the floor. Realizing that he can't stick to the ceiling like the roaches, Oggy freaks out and clings to the ceiling's fabric before ripping it off. Oggy falls onto the floor, landing on the mouse traps that he has set before.
On what seems to be their final raid, the roaches use a bottle of champagne as a rocket to make a quick getaway. Oggy (who is now desperate) begins to chase them yet again. However, he lands inside his washing machine, Dee Dee then turns it on, causing Oggy's head to puff up.
After a while, Oggy walks towards his fridge, saddened that the Cockroaches had won. He opens the fridge to see that the Cockroaches had left him a single item: an open can containing one bean. The now-exasperated Oggy eats the bean while watching television. The bean makes Oggy fart, causing the Cockroaches in the distance to laugh at him.
