Abstract: A toilet training system is installed upon a conventional toilet. The system includes a decorative form containing a cartoon or a design, and a related cartoon or design on the underside of the lid of the toilet. The form comprises a first upstanding part such as cartoon head, and a second part defining, for example, a depending related face. The first part of the decorative form is seated upon the upper surface of the toilet tank projecting upwardly above the toilet tank, while the second part or face of the character depends downwardly over the front face of the toilet tank. The full extent of the form is visible when the lid is closed. A face, similar to the second part is secured to the underside of the lid seat. Consequently, when the lid is raised, visual continuity of the cartoon character is maintained, so that the child being trained focuses on the decorative form and responds more readily to toilet training instructions.
