Riverhead Middle School, Also known as the Nick Jr. School Set, is a now defunct middle school located in Long Island, New York. It features many animals that are outside, such as squirrels, bats, skunks, killer rabbits, chipmunks, raccoons and mice and graffiti too. It was built in the 1950s and abandoned since 2012. It became a Nick Jr. School Set back in 2007-2012 when they use to film promos and bumpers for various Nick Jr. shows such as Dora, Blue, Wonder Pets, Wubbzy and Kai-Lan until it was abandoned until further notice. It was demolished between 2018 and 2020. The school also has its own class pet: a hamster, until it ran away from its cage.
