Bremen: From the World of Zootopia

Bremen: From the World of Zootopia (mostly shortened to just Bremen) is an upcoming American 3D computer-animated musical comedy film produced by Walt Disney Animation Studios and released by Walt Disney Pictures. The film is a loose spin-off of Zootopia, directed by Steven Clay Hunter and Trent Correy and stars the voices of Zac Efron, Ed Sheeran, Demi Lovato, Donald Glover, Michael C. Hall, Leslie Odom Jr., Allison Tolman, Judy Greer, Shakira and Alan Tudyk, the latter two of whom reprise their roles from the previous film. The film focuses on four anthropomorphic "domestic" animals from the boonies of Bremen, who leave for Zootopia to become a rock band, naming themselves after their hometown.

Plot
Hunter Barks lives in the small podunk town of Bremen. Ever since his father left and never returned, Hunter has taught himself to play the keyboard. Despite his mother's disappointment of her husband leaving, she has supported Hunter's desire to be a musician. One day Hunter is in the middle of town trying to play a song to passerbys when he is suddenly approached by Garret Coops, a traveling guitarist who joins him ("Dreams"). Garret reveals that he has been trying to leave town himself, but wants to go solo and offers a truce with Hunter that they get out together. While Martha, Hunter's mother, is saddened to see him go, she understands and Hunter and Garret leave the next day.

They ride the bus and stop by Scranton Junction where they plan to go their opposite ways. However, Hunter and Garret end up rescuing Cleo Kadenza from some bullying ocelots. After saving her, Cleo begins to follow Hunter and Garret around with enthusiasm. She sees their instruments and reveals that she is a drummer. Despite having no intention of staying together, she convinces them to play a brief stint at a small club nearby. Hunter and Garret manage to come together thanks to Cleo ("Forever") and mutually agree to stick together and find a bassist.

Elsewhere, bassist Oscar Hoofman is kicked out by his group due to his lateness. He runs afoul of a porcupine gang and ends up running into Hunter, Garret and Cleo. The four hide out in a hovel where Oscar reveals his ability to play a bass using a unique device of his own making. The three are stunned when he reveals that he has perfect pitch ("Give Me One Reason"). The porcupines find them and they run; resolving to stack atop each other, they hop aboard a train and escape. Hunter realizes that he has a full band and they all agree to name themselves Bremen after Hunter's town. The group decide that their next stop needs to be Zootopia.

Bremen manages to arrive in Zootopia (in a callback to the original) as they take in the sights ("Try Anything"). They decide that they must meet singing sensation Gazelle so that they can make it big. After accidentally jaywalking, they run afoul of pregnant Officer Swinton who chases them throughout the film and fails due to her condition. They manage to duck into a friendly neighborhood where they meet Roland, a bear who runs a food stand. Wanting attention, he asks the gang to help bring in customers and they oblige ("Walk This Way").

Trivia

 * The placement of the Bremen band members is reminiscent of the Shonen Jump manga series Bremen by Haruto Umezawa.
 * This movie answers the question about domestic animals in the world of Zootopia. While they exist, they are not as common and are considered a minor breed.
 * Swinton is depicted as a pregnant police officer. This is a nod to Allison Tolman's role as Molly Solverson in the television series Fargo.
