Continuity: When Ms. Waxelplax tries Timmy's homemade golf course, her ball hits a windmill, knocking it loose. The windmill flies forward like a propeller but on the next cut, flies sideways.

Continuity: When HP does his ball for hole 1, it flies up, and falls diagonally, but at the next shot, it falls vertically.

Factual error: In "Vicky Loses her Icky", when evil Ms. Waxelplax nails up the classroom door, the nails and holes are all crazy and do not match places (using a mirror, that is).
