Goofs

 * In the end, when D.W. is having a yard sale to pay for the damages to Arthur's glasses. The animation is really off and not proportioned correctly. It doesn't even look like D.W. at times!
 * Wouldn't Arthur's parents call the police if the Tibbles broke Arthur's glasses for fighting with him?
