The twenty-seventh episode of the first season of Dennis the Menace (1986).
After he gets hit on the head during a game of kickball, Dennis has visions of events that haven't occurred yet, all of which become true, from Mr. Wilson's basement getting flooded, Henry getting thrown into a pile of garbage, and Margaret's new dress getting ruined when the kids go on a field trip to a candy factory. Dennis' psychic ability makes the news and a reporter asks what his next prediction will be just before he gets hit on the head again. After he recovers, he says there's going to be a snowstorm even though it's the month of June. However, his vision proves false, leaving the town folk really hot and bothered as they've all overdressed for the occasion. Afterward, Dennis vows never to play kickball again.
Dennis and the Kangaroo Cavalry
The Mitchells and the Wilsons visit Australia to attend the Royal Order of the Kangaroo Convention in which Henry and Mr. Wilson are members. The group encounters real kangaroos running amok all over the city when a drought drives them out of the forest as they search for water. Henry and Mr. Wilson try to help the few game wardens round them up so they can be transported to safety. Their efforts fail, but Dennis and Wally, a young Australian boy are able to use their harmonica and flute to get them to the airport where they can be safely transported. As a reward, Mr. Wilson gives Wally the golden boomerang he received at the convention.
After Ruff eats the leftover food that the family was to have for lunch, Dennis, Gina, and Joey do what they can with the remaining food (and other items) to make the special spaghetti meal Henry and Mr. Wilson wanted. Their efforts lead to a lunch with soap bubbles, and a big mess in the kitchen to Alice's shock when she arrives home.
