Nearly 200 Audio-Animatronics figures perform in the Under the Sea: Journey of the Little Mermaid attraction. The Under the Sea scene alone has 128 figures, including 50 spinning starfish.
The Little Mermaid animatronic in the Under the Sea scene of the Journey of the Little Mermaid attraction cost $7 million to develop for the Disney California Adventure version of the attraction. This was in part because of the animatronic hair that was replaced shortly after opening and was carried over to the Florida version.
The figures of Grumpy, Doc, Bashful, Sleepy, and Happy, seen in the cottage near the end of The Seven Dwarfs Mine Train, originally appeared in Snow White’s Scary Adventures, a Magic Kingdom attraction now the site of Princess Fairytale Hall. The two vultures perched on the jib crane near the mine entrance are styled after the vultures in the film and also originally appeared in the Snow White’s Scary Adventure attraction.
At one point in time, when Princess Jasmine first appeared in Mickey's PhilharMagic, the scent emitters would emit the scent of jasmine. Disney discontinued this effect due to allergies of some guests.
Imagineer Darryl Picket not only became the voice of the Walt Disney World Railroad in 2012, but he also designed the decorations in the Jungle Cruise that read "Kittens Free to a Good Home" and the menu where every item tastes like chicken.
The Dwarfs cottage on The Seven Dwarfs Mine Train is a meticulously detailed representation of the cozy home seen in the classic film, down to the wisteria vine and birdhouse at the front door.
Famed voice actor Paul Frees is the voice of the Ghost Host in The Haunted Mansion, the original Auctioneer in Pirates of the Caribbean (prior to the 2018 refurbishment), and Captain Nemo in the extinct 20,000 Leagues Under the Sea. Frees' other credits include Ludwig Von Drake, Boris Badenov (The Rocky and Bullwinkle Show), Toucan Sam, and much more.
The queue for The Seven Dwarfs Mine Train features the song, "Music In Your Soup," a song that was cut from the film but re-recorded for the attraction.
In The Seven Dwarfs Mine Train attraction, the shadows of the Dwarfs marching homeward along the track on the lift inside of the mine were rotoscoped from the scene in the original film where the Dwarfs march across a log bridge, singing “…home from work we go.” (Rotoscoping is a technique where the movements of a figure in original live or animated footage are copied, or traced, frame-by-frame).
In the Under the Sea: Journey of the Little Mermaid attraction, a special skin technology had to be incorporated into the Audio-Animatronics figures for Ariel, King Triton and Ursula since they have so much skin exposed.
Next to Doc’s workstation in the mine scene of The Seven Dwarfs Mine Train, the carved wooden clock is a replica of the one seen in the film. It features figures of two miners striking an anvil. As in the film, that motion signals the start of the beloved song, “Heigh-Ho.”
The mural in the Grand Canyon Concourse of the Contemporary Resort was designed by Imagineer Mary Blair. Mary also designed much of the artistic style for "it's a small world". In the mural, Mary deliberately placed a 5-legged goat on one of the cliffs. Allegedly, it was an intentional way of honoring the Native American tribes that resided around the Grand Canyon that believed nothing in life, including artwork, could be “perfect.”
An 86-foot long, hand-painted mural greets guests in the loading area of Under the Sea: Journey of the Little Mermaid. The mural depicts Ariel at dusk.
The Ursula figure in Under the Sea: Journey of the Little Mermaid is the largest Audio-Animatronic figure in the show at 7-feet tall and 12-feet wide. She also has a squash-and-stretch function in her torso and flexible materials so she can bounce along with the music.
On the backside of the sign for The Barnstormer Featuring the Great Goofini you will see that Disney re-used the old signage for the original attraction.The pieces can be rearranged to spell out Wiseacre Farm.
When Disney constructed Mickey Mouse Review and Hall of Presidents they were constructing two large scale animatronic stage shows that required a significant amount of computing power. The buildings are connected so that they can share this infrastructure and during testing some of the dialog from each show played at the other venue.
At the third interactive station in The Seven Dwarfs Mine Train queue, “Vault” is carved into the wooden crosspiece, or lintel, above the doorway. This is a reference to the scene in the film where Dopey opens the vault and throws in a bag of gems, then locks the door with a key. For safekeeping, Dopey hangs the key to the vault on a peg next to the door. The key hangs on a peg next to the entrance to the vault in the queue as well.
The individual mine cars in Seven Dwarfs Mine Train are designed to reflect similar vehicles that appear in the film: handmade of wood by the Dwarfs, shaped with an ax, and used to haul rocks and jewels. Hand-hammered metal bands and nails are used to bind the wood. In the film, the mine cars sit in a cradle that allows them to be tipped to unload their contents. Here, the cradle design allows the cars to swing back and forth as they carry riders along the winding track.
In the bushes surrounding Mad Tea Party there is a tribute to former Disney employee Randy Pausch. Randy is best known as the author of "The Last Lecture", a book describing his life and his battle with pancreatic cancer. The tribute comes in the form of a quote on an Alice in Wonderland themed leaf. The quote reads, "Be good at something: It makes you valuable... Have something to bring to the table because that will make you more welcome." - Randy Pausch
Each scene of Under the Sea: Journey of the Little Mermaid was first built as a one-quarter-inch scale model and then as a one‑inch scale model, so Imagineers could “ride” through the attraction scene-by-scene before full construction began.
