Slappy Blackhead's Way Cool Journey Through Time is a movie that Arthur and D.W. went to instead of Doll Story 2 with Muffy, Francine and Buster in "D.W.'s Time Trouble". It is a time traveling movie where a mischievous prankster goes back in time to pull pranks on different people including his principal. Many other third graders also went to the showing.
- The movie may be a combination parody of Bill & Ted's Excellent Adventure, Ferris Bueller's Day Off, and Back to the Future. The use of a bike as a time machine may also be a reference to The Time Bike.
- Little kids call it Sloopy Bloopy.
