Gloomytown is the location where the stories of Wishes Upon The Cosmic Clock & Woah! Signal mainly take place. It is an average-sized city, set in an Earth where instead of humans, the world is populated by Gloonsters. The residents in Gloomytown mainly speak British English.

Every two decades, a periodic comet known as the Wishmaker's Comet becomes visible in Gloomytown's sky, where legend says that if you make a wish upon the comet, it will surely come true.

There also exists a museum & an Astronomer Hobbyist Club, of which, as of 2031, its known members include Madison, Stella, & Braker.
