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 the worker scares Greg and Rowley by saying someone 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 book and the film are the only time the Cranium Shaker appeared. At the top of the ride, Rowley and Greg then confess their dirtiest secrets to each other. In the book only Greg goes to the ride while Rowley goes on the kiddie rides and later, Rowley buys a "I survived the Cranium Shaker" shirt without even going to the ride.

While this ride is indeed fictional, during the movie 'Dog Days', it was filmed on a ride called "Revelation" at an amusement park called Playland in British Columbia, Canada.

Trivia
