Barnaby is a goofy dog who is the clown/magician known as "Barnaby the Great". He is known for saying, "Ah-hee-ee-ee-ee-ee!" whenever he laughs and sounds like he's from the south. His tricks don't always work out the way he wants them to. He is good friends with Lionel and Q.T.. He also gets scared easily. He often hums his signature song "I'm Just a Lucky Dog." He comes from a big family: Edison Bowser (who invented flea powder), Isadoga Bowser (a famous dancer who perfected the "Dog trot"), Julia Bowser (his favorite as she invented the hot dog) and his famous Uncle Lattimer Bowser III.
