Marky

Marky is mild-mannered, often not really caring what the other two roaches are doing. He's the middle child. Although he originally loved causing mischief just like the other cockroaches, he's grown to be more laid-back in later episodes, though he still enjoys hanging out with Joey and Dee Dee and causing general chaos as he always has. His hobbies include dating girls—even puppets—and reading books. He also has bad breath, as revealed in the episodes "It's a Small World" and "Itsy-Bitsy Oggy" (how he can tolerate his own bad breath is debatable, since he couldn't stand the smell of gas in French Fries).

It has a gray body, a green head with pink eyes, and a somewhat slender build. It has curly antennae and wears white gloves.
