D.B. was born like an ordinary frog. Born in a small pond in Zootropolis, with his many siblings as tadpoles. But just like ordinary frogs, the tadpoles left the pond and lived their own lives when they have fully grown into their frog forms. That’s what D.B. (who wasn’t named that at birth, and the tadpoles weren’t named at all) did. What he wanted to do with his life, was entertain people and make them laugh. He didn’t care who or where he’d perform his comedic acts. In fact, he didn’t care too much about what other people think at all.

D.B. found nowhere decent to live, so he found an alley, and a dumpster to sleep in. In that dumpster, he found an old unicycle and an airhorn. Right away, he thought these were just the things to perform his tricks with. He was pretty much a public nuisance, almost everyone was annoyed and disgusted by his presence and constant sounds he made with his airhorn. D.B. was his nickname he went by, since everyone on the street would say, “Here come dat boy!” every time they saw him. He didn’t have a really entertained audience, like he expected. But D.B. could care less about other people’s thoughts, but he didn’t want his reputation to be all negative.

Then later on, he met Ceylon, who practiced clown tricks in the alley. He loved seeing his tricks and performances he practiced. The young dog boy couldn’t help but sympathize the frog’s life, having to live in a dumpster and people letting him down every time he was seen in public, and offered him to join him and make his reputation better. Since then, D.B. and Ceylon became great partners and the best of friends.
