Mr. Otterton

Emmitt Otterton is a North American river otter from the 2016 Disney animated film Zootopia. The husband of Mrs. Otterton and father of two children, he turns savage and goes missing. The search for the missing otter becomes the driving force of the film.

Role in the film
In the film, Mr. Otterton had urgent matters to discuss with his close friend and employer Mr. Big. In response, a limousine escort was sent by the crime boss to pick him up. During the escort, however, Otterton is shot by a sniper with a pellet made from night howler serum, causing Otterton to become a savage beast. When his driver Mr. Manchas overhears the commotion, Otterton attacks him, maiming the jaguar's eye and forcing the car to stop while Manchas barely manages to get away from the now feral otter. In his last moments of sanity, Otterton yells "Night Howlers." as a warning to what had happened (being a florist) before he scurries off into the forest. He is eventually captured by wolf security forces under the orders of Mayor Lionheart and incarcerated at Cliffside Asylum with other citizens who have gone savage.

More than a week later, Mr. Otterton is located by Officer Judy Hopps and Nick Wilde, who were sent by Mrs. Otterton to find him, but receive a fierce snarl from the otter, his sentience apparently absent from his mind. After the asylum is raided, Otterton is moved to a hospital, though still trapped in his feral state. When Mrs. Otterton visits her husband, she is heartbroken to see the Emmitt she knew to be lost.

When it is discovered that the night howlers were the cause of the outbreak as an elaborate plot by Assistant Mayor Bellwether, an antidote for the savaged citizens is found. Among them, Mr. Otterton is eventually cured of his savage condition and happily reunites with his wife.

During the end credits, Mr. and Mrs. Otterton are seen at a concert held by Gazelle, where they happily dance together.
