Prince Gumball and Marshall Lee Abadeer are best friends. Really close. Close enough to not rat out the other after killing someone. They've been together since they were little. They only talk to each other. Refuse to make other friends. Both don't have a family.
They aren't seen away from each other. Not even for a second. Where one is, you'll see the other. School, store, park, anywhere. Teachers are getting tired of Prince Gumball being around such a "bad influence" and decide to split them up for a project. How far will this go before the teachers realize these two won't split?
