Roger Rabbit's Car Toon Spin is a great dark ride in Mickey's Toontown whose queue may just be as interesting and fun as the ride itself. Every twist and turn leads to a new set and new things to see.
Of course, the Dip makes an appearance (apparently the cans are actual props from the movie) with a recipe should you desire to make your own.
Message boards are littered with references to not only Who Framed Roger Rabbit, but other animated movies as well.
And of course, no queue is complete without a great crate to enjoy!
