Sky Rat (cancelled Nickelodeon animated series)

Sky Rat was a proposed American animated television series that would have been aired on Nickelodeon. The series proposal was created by Hey Arnold!, Dinosaur Train, and Ready Jet Go! creator Craig Bartlett, who would have served as the executive producer. The synopsis was given as "When a rat who has amnesia meets pigeons, they teach him to fly!" When Bartlett announced the series several years ago, he said he based the series on his pet rat.

In an online interview on The Arun Mehta Show on October 4, 2017, Bartlett confirmed that with the focus on getting Hey Arnold!: The Jungle Movie going, Nickelodeon was not interested in approving Sky Rat for production.
