Mr. Otterton

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

Zootopia
In the film, Mr. Otterton had urgent matters to discuss with his close friend and employer Mr. Big. He contacted Mr. Big and told him to send a limousine. Meanwhile he bought a pawpsicle from Nick Wilde and went to the Mystic Springs Oasis. When Yax and Nangi walked him out, Mr. Manchas picked him up in a limousine and started driving him to Mr. Big's mansion.

That night during the escort, however, Otterton is shot by a sniper with a pellet containing night howler serum, causing Otterton to revert to a savage beast. In his last moments of sanity, Otterton madly yells "night howlers" as a warning to what had happened. When Manchas overhears the commotion, Otterton attacks him, brutally maiming the jaguar's eye and forcing the car to stop while Manchas barely manages to get away from the now feral otter. With a snarl, Otterton then scurries off into the night. He is eventually captured by wolf security forces under the orders of Mayor Lionheart and incarcerated at Cliffside Asylum with other predatory 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 only 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 one day 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, happily dancing together.
