Cranium Shaker
The Cranium Shaker is a scary thrill ride that Greg goes on at the board walk in the end of Dog Days. In the movie, Greg goes on the Cranium Shaker with Rowley. In the movie two teenage girls scare Greg and Rowley by saying some one got decapitated while riding. Greg says in his journal that Rodrick has gone on about a billion times and that you can't call yourself a man until you ride it. After Greg got off the Cranium Shaker, he nearly threw up. The Dog Days movie and films are the only time the Cranium Shaker appeared. At the top of the ride,
Rowley and Greg confess their dirtiest secrets to each other.
While this ride is indeed fictional, during the movie Dog days it was filmed on a ride called "Revelation" at the amusement park Playland in British Columbia, Canada.
