Pest Pupil

Baby Huey, the over-sized duck, is enrolled in kindergarten but his size and clumsy attempts to fit in causes such havoc that he is expelled by the teacher. His mother then hires a private tutor, who is led a life of misery due to Huey's efforts to do good that unintentionally backfire. But the tutor winds up in the ocean---unless Huey lived on a shark-invested lake---and and is about to become a shark meal but Huey saves his life...and gets his diploma as a reward from the grateful tutor.
