Cartoon cameos are all over "Roger Rabbit," but one scene in particular is so jam-packed it requires a lot of attention. When Doom's dip-spewing tractor rams a hole in the Acme warehouse, something like half the population of Toontown shows up to see what's going on.
The hole reveals Acme's warehouse is built outside the flowers and trees from the Silly Symphony "Flowers and Trees." Some of the characters we've seen before return to speculate on Doom's true identity, along with Pinocchio, Woody Woodpecker, and Disney's Big Bad Wolf (who, in a gag fast-paced enough to be an honorary Easter egg, says Doom wasn't a sheep while pulling off the proverbial sheep's clothing). The best we can do for the rest of the crowd is a partial list, with some explanations for the deeper cuts: Bambi, Goofy, Dopey, Pluto, Minnie Mouse, Sylvester and Tweety, Peter (of "Peter and the Wolf"), the singing harp from "Mickey and the Beanstalk," José Carioca of the Three Caballeros, Speedy Gonzales, Foghorn Leghorn, Sam Sheepdog, Marvin the Martian, Snow White, and Tweedle-Dee (or is it Tweedle-Dum?).
Even the police squad clearing everyone out is full of stars. Besides Porky Pig letting us know that's all, folks, there's Mickey's pal Horace Horsecollar and enemy Peg Leg Pete.
