Jack is a cat with an olive body, yellow eyes, red nose, pale pink stomach, and white feet.He loves money, but his efforts always fall short, usually ending with him getting swatted or beaten up. Even though he is the shortest roach in the group, he is the most intelligent, always being the brain in the plans, but is sometimes forced to go alone because Marky and Dee Dee often think that his plans are stupid. Joey (born 15 June 1991) is a cockroach with a purple-pink body, a pink right eye (originally red), a yellow left eye, lavender head, black nose, and black feet.His eyes are red again in the ending of the episode "Teleportation" where he is stuck in ice cubes. His hobbies are dating puppets and reading books he also has bad breath as revealed in "It's a Small World"/"Itsy-Bitsy Oggy".
In most episodes, he is shown with Dee Dee as his partner.
Although Marky originally used to love causing mischief just like Dee Dee and Joey, he has grown to be more laid-back as the series progress.
Oggy usually spends his time either watching TV or doing housework - when not chasing the cockroaches.
