There are several video games based on the films, and the characters have made appearances in other crossover video games.
- The Little Mermaid is a video game was developed by Capcom for the NES and Game Boy, and published in 1991. It is a single player side-scrolling action game where the player controls Ariel on a quest to defeat Ursula. Ariel has already met Eric, and they plan to wed, but Ursula has taken control of the ocean. So Ariel (after explaining what's going on to Eric) becomes a mermaid once more and sets off to rescue the sea. The game takes place from a side view and Ariel (swimming most of the time, but hopping around on the land occasionally) can shoot bubbles to trap her foes and can then throw them at each other. She can also dig through sand to find treasure and pick up sea shells to break chests open with. The treasure she finds in the sand is usually just bonus points, but the treasure you find in chests will increase your bubble's power and range. The gameplay is similar to other Capcom games such as Chip 'n Dale Rescue Rangers and DuckTales in that Ariel shoots air bubbles from her tail that when they hit certain enemies, can be picked up and thrown at other enemies or bosses. Ariel can also collect icons scattered throughout the levels to restore health, gain extra lives, or increase the range/power of her air bubbles.
There are some differences between the NES and the Game Boy versions. When a stage begins, Ariel descends from the top of the screen to the recommended starting point in the NES version, but just starts out in the recommended position in the Game Boy version. The featured SFX are different in both versions. The start of the stage's BGM can be heard only once in the NES version; although the whole BGM can be repeated in the Game Boy version. The stage backgrounds were more restricted in the Game Boy version than in the NES version. When you lose a heart, the heart turns into a heart frame in the NES version, but disappears in the Game Boy version. The key scales of the Boss BGM are different in both versions. The BGM speed in the NES version is much faster than in the Game Boy version.
- Ariel the Little Mermaid is a video game published by Sega in 1992 for the Mega Drive/Genesis and Game Gear (a Sega Master System version was released by Tec Toy in Brazil). The game lets the player control either Ariel or King Triton to defeat Ursula. Rescuing requires the player to simply swim into the unfortunate little victims as they hang about at fixed places in the watery world; while fending off and dodging enemies like eels, clams, sharks, and several other sea meanies. Friends like Flounder and Sebastian can also be summoned for a little helping hand.
- The Little Mermaid 2: Pinball Frenzy is based on The Little Mermaid II: Return to the Sea. It is a pinball video game developed by Left Field Productions and published by Nintendo for the Game Boy Color handheld video game console. It was first released in North America, and was later released in PAL regions.
- The Little Mermaid: Magic in Two Kingdoms, by Buena Vista Games, was released for the GBA. A The Little Mermaid hand-held LCD game from Tiger Electronics was also released. The most recent game released was Disney's The Little Mermaid: Ariel's Undersea Adventure which was released on the Nintendo DS on October 2, 2006.
Characters and the setting from the first film appear in Disney/Square's Kingdom Hearts series of video games. Ariel appears as a party member, while Ursula is the boss in the world of Atlantica and one of the members of Maleficent's inner circle. Other characters from the film also make appearances.
Several attractions based on The Little Mermaid have been released. Mermaid Lagoon at Tokyo DisneySea is a themed land made to look like the Palace of King Triton and features fanciful seashell-inspired architecture. It includes the meet-and-greet attraction Ariel's Grotto, as well as the parachute jump–style ride Jumpin' Jellyfish (both also present in Disney California Adventure). King Triton's Carousel of the Sea is a carousel at Disney California Adventure, that uses seahorses, flying fish, whales, dolphins, sea lions, otters and garibaldi. Voyage of the Little Mermaid is a live show attraction at Disney's Hollywood Studios in Florida that features puppets and live actors. Other attractions based on the film include The Little Mermaid: Ariel's Undersea Adventure, a dark ride attraction in Paradise Pier and the Magic Kingdom in New Fantasyland.
Ariel is part of the Disney Princess franchise, an extensive line of merchandise that includes dolls, sing-along videos, and a variety of other children's products, apparel, and even adhesive bandages. Ursula, on the other hand, is part of the official line-up of the Disney Villains franchise.
Many characters from the franchise appear in the Disney Channel series House of Mouse. Some of them also appear in the series' spin-off film Mickey's Magical Christmas: Snowed in at the House of Mouse, and Ursula appears as one of the main villains in Mickey's House of Villains. The characters also appear at Walt Disney Parks and Resorts as meet-and-greet characters.
In The Little Mermaid, Ariel, a sixteen-year-old mermaid princess, is dissatisfied with life under the sea and curious about the human world, despite the warnings of her father King Triton and court musician Sebastian, the crab, that contact between merpeople and humans is forbidden. One night, Ariel, her best friend Flounder and an unwilling Sebastian travel to the ocean surface to watch a celebration for the birthday of Prince Eric, with whom Ariel falls in love. A sudden storm hits, and Eric almost almost drowns saving his dog Max but is saved by Ariel, who drags him to the beach. She sings to him but dives underwater when Max returns to Eric. Upon waking, Eric has a vague impression that he was rescued by a girl with a beautiful voice; he vows to find her, and Ariel vows to find a way to join Eric.
King Triton and his daughters notice a change in Ariel, who is openly lovesick. King Triton questions Sebastian about Ariel's behavior, during which Sebastian accidentally reveals the incident with Eric. King Triton furiously confronts Ariel in her grotto, using his trident to destroy her collection of human treasures. After King Triton leaves, a pair of eels, Flotsam and Jetsam, convince a crying Ariel that she must visit Ursula, the sea witch, if she wants all of her dreams to come true. Ursula makes a deal with Ariel to transform her into a human for three days. Within these three days, Ariel must receive the 'kiss of true love' from Eric; otherwise, she will transform back into a mermaid on the third day and belong to Ursula. As payment for legs, Ariel has to give up her voice, which Ursula takes by magically removing the energy from Ariel's vocal chords and storing it in a nautilus shell.
Eric and Max find Ariel on the beach. He initially suspects that she is the one who saved his life, but when he learns that she cannot speak, he discards that notion. Nonetheless, Ariel spends time with Eric, and at the end of the second day, they almost kiss but are thwarted by Flotsam and Jetsam. Angered at their narrow escape, Ursula takes the disguise of a beautiful young woman named "Vanessa" and appears onshore singing with Ariel's voice. Eric recognizes the song and, in her disguise, Vanessa/Ursula casts a hypnotic enchantmenton Eric to make him forget about Ariel. The next day, Ariel finds out that Eric will be married to the disguised Ursula on a ship. She cries and is left behind when the wedding barge departs. Scuttle discovers that Vanessa is Ursula in disguise, and informs Ariel. As Ariel and Flounder chase the wedding barge, Sebastian informs King Triton, and Scuttle is assigned to literally "stall the wedding." With the help of various animals, the nautilus shell around Ursula's neck is broken, restoring Ariel's voice and breaking Ursula's enchantment over Eric. Realizing that Ariel was the girl who saved his life, Eric rushes to kiss her, but the sun sets and Ariel transforms back into a mermaid. Ursula reverts to her true form and kidnaps Ariel.
King Triton appears and confronts Ursula, but cannot destroy Ursula's contract with Ariel. King Triton chooses to sacrifice himself for his daughter, and is transformed into a polyp. Ursula takes King Triton's crown and trident, which was her plan from the beginning. Ursula uses her new power to gloat, transforming into a giant, and forming a whirlpool that disturbs several shipwrecks to the surface, one of which Eric commandeers. Just as Ursula is set to use the trident to destroy Ariel, Eric turns the wheel hard to port and runs Ursula through the abdomen with the ship's splintered bowsprit, mortally wounding her. With Ursula gone, her powers are broken and the polyps in Ursula's garden (including King Triton) turn back into the old merpeople. Later, after seeing that Ariel really loves Eric and that Eric also saved him in the process, King Triton willingly changes her from a mermaid into a human using his trident. She runs into Eric's arms, and the two finally get married.
The plot of The Little Mermaid II: Return to the Sea focuses on Ariel's daughter Melody who longs to be a part of the ocean and is ultimately manipulated by Ursula's vengeful sister, Morgana, into stealing the trident for her. The film is essentially a re-telling of the first film, to the point that Morgana has two manta ray cohorts very similar to Flotsam and Jetsam, desires the trident and revenge against King Triton, and is even voiced by Pat Carroll.
The Little Mermaid: Ariel's Beginning is set before the events of the original film, in which King Triton has banned music from Atlantica, and Ariel, her sisters, Sebastian and Flounder rebel against this new law while a greedy palace official, Marina Del Rey, seeks to claim Sebastian's position for herself. It is really clear that Ariel is the youngest daughter of King Triton in all the franchise.
The Little Mermaid was originally planned as part of one of Walt Disney's earliest feature films, a proposed package film featuring vignettes of Hans Christian Andersen tales. Development started soon after Snow White and the Seven Dwarfs in the late 1930s, but was put on hold due to various circumstances.
In 1985, The Great Mouse Detective co-director Ron Clements discovered a collection of Andersen's fairy tales while browsing a bookstore. He presented a two-page draft of a movie based on "The Little Mermaid" to CEO Michael Eisner and Walt Disney Studios chairman Jeffrey Katzenberg at a "gong show" idea suggestion meeting. Eisner and Katzenberg passed the project over, because at that time the studio was in development on a sequel to their live-action mermaid comedy Splash (1984) and felt The Little Mermaid would be too similar a project. The next day, however, Walt Disney Studios chairman Katzenberg greenlit the idea for possible development. While in production in the 1980s, the staff found, by chance, original story and visual development work done by Kay Nielson for Disney's proposed 1930s Anderson feature. Many of the changes made by the staff in the 1930s to Hans Christian Andersen's original story were coincidentally the same as the changes made by Disney writers in the 1980s. That year, Clements and The Great Mouse Detective co-director John Musker expanded the two-page idea into a 20-page rough script, eliminating the role of the mermaid's grandmother and expanding the roles of the Merman King and the sea witch.
In 1987, songwriter Howard Ashman became involved with the writing and development of The Little Mermaid after he was asked to contribute a song to Oliver & Company. He proposed changing the minor character Clarence, the English-butler crab, to a Jamaican Rastafarian crab and shifting the music style throughout the film to reflect this. At the same time, Katzenberg, Clements, Musker, and Ashman revised the story format to make Mermaid a musical with a Broadway-style story structure, with the song sequences serving as the tentpoles of the film. Ashman and composer Alan Menken, both noted for their work as the writers of the successful Off-Broadway stage musical Little Shop of Horrors, teamed up to compose the entire song score.
The first film's soundtrack, The Little Mermaid: An Original Walt Disney Records Soundtrack contains the songs from the film written by Menken and Ashman, as well as the film's score composed by Menken. The album received the Academy Award for Best Original Scoreand the Golden Globe Award for Best Original Score. As of February 2007, the album is certified 6x Platinum by the RIAA. In 2010, Rhapsody (online music service) called it one of the all-time great Disney & Pixar Soundtracks.
Apart from the original soundtrack, The Little Mermaid has inspired several more albums. Sebastian from The Little Mermaid and Sebastian: Party Gras! contain songs are cover versions of classic calypso or reggae songs. All of the songs are performed by Samuel E. Wright as Sebastian the crab, with the exception of "Dancing Mood" and "Dance the Day Away", which are performed by Jodi Benson as Ariel, who also joins Sebastian on "Day-O". Jason Marin plays the speaking role of Flounder in the beginning of some tracks. The Little Mermaid: Songs from the Sea is a concept album; listening to the tracks in order will present the story of a typical day in the life of the mermaid Ariel(set sometime before the events of the first film).
Disney's The Little Mermaid: Original Broadway Cast Recording is the cast album for the musical The Little Mermaid. It features performances from the show's cast, which includes Tituss Burgess, Sherie Rene Scott, Norm Lewis, Eddie Korbich, and newcomer Sierra Boggess as Ariel, the Little Mermaid.
