Super Mario Bros. & Friends: The Search for Papa/References

Mario is Missing

 * Type: Video game
 * Origin:  United States
 * The plot of this movie appears to be loosely based on this game.
 * The places Mario and Luigi go to throughout the movie are the same places that are accessible in the PC version of that game, in that order.
 * The ending where Luigi tears off Mama's dress and finds the key inside is very reminiscent of the ending of the PC version of that game, where he did the same thing to Bowser with his shell.

Shrek

 * Type: Feature film
 * Origin:  United States
 * The beginning scene where Papa's story is told in a book is reminiscent of a similar scene from the first two movies and in Shrek Forever After, which itself is a parody of how various Disney films based on fairy tales opened.

Teenage Mutant Ninja Turtles II: The Secret of the Ooze

 * Type: Feature film
 * Origin:  United States
 * The scene where Mario and Luigi happen to find Hatsune Miku performing on stage and join her in her song is reminiscent of a scene in that film where the Turtles end up in the middle of a Vanilla Ice performance and join them.

Super Mario Bros.: The Great Ladder Race Game

 * Type: Toy
 * Origin:  United States
 * The sequence towards the end of the film where Mario and Luigi attempt to climb continuously rotating ladders is reminiscent of this game.

Caillou Gets Grounded: A Tale of Two Dimensions

 * Type: Web movie
 * Origin:  United States
 * The sequence towards the end of the film where Mario and Mama fight each other is reminiscent of the fight between the Caillou and Boris robots in that film, even using the same music (which is itself taken from the second stage of the final boss from New Super Mario Bros. Wii).
