Jakers The Adventures of Piggley Winks (2003)

Young Piggley’s insecurity rises when he discovers that his teacher, Mr. Hornsby, is coming to his house for supper. Piggley is certain he's going to “grade” the Winks family and that they’ll come up woefully inadequate! So Piggley and pals hatch a plan to make sure the Winks family gets passing marks. Much to Piggley’s surprise, he discovers that Mr. Hornsby is just a regular person - and not so intimidating after all.
