Danny and his friends have traveled to the circus and boarded the circus train, Casey Jr. While onboard they realize that one of the female elephants was expecting and met Dumbo, a young elephant with large, floppy ears. While the other female elephants ridiculed him, Danny and the gang didn't laugh at him because they thought that they look good on him. Later, when his mother, Mrs. Jumbo was imprisioned, they met Timothy Q. Mouse and they realized that he could use his large, flappy ears to take flight and he became the star of the circus and his mother was let out and they share a private coach at the rear of the train. After that, Timothy Q. Mouse and the Crows decided to join Danny's Adventure team.
