Dee Dee is a cockroach who is always hungry and eats everything. He acts a bit childish and immature. He is also the most sensitive as he is seen crying over food, the loss of his brothers and even his failed attempts to appear in an opera show with Jack in one episode. His appetite sometimes reaches insane levels, often leading to the consumption of larger animals or other things (such as hyenas in one case and the effects of a poisonous mushroom in another). another case is insects. He even tried to eat elephants, Oggy, Jack and a wild boar. He is usually the bravest of the group as he has even handled larger animals such as penguins for eggs, octopuses for arms, and a herd of elephants so he can eat one of them. — but his efforts are often wasted when he is beaten. Sometimes, Dee Dee gets tired of Joey's controlling antics and will side with Marky when he feels Joey is being unfair or too assertive.
