The Cowbell Thing, also known as the Agogo, is a dark gray humanoid robot. Its head droops loosely from its neck and resembles a large cowbell, has two large exes where its eyes would be, and contains an elongated tongue resembling, and functioning similarly to, a bell's clapper. As it moves, it produces a distinct cowbell sound whenever its tongue collides with its mouth. Because it is inorganic and has no weakpoints, the Cowbell Thing is unable to be harmed.
