This is a request by  safetymaskfan123 for Princess Ariel and her daughter Melody from Disney's The Little Mermaid franchise being put into a double peril. Both of them have been trapped in a room which is simultaneously with brackish water and gas. Though they have gas masks, but that won't help them with the water. Which is an ironic peril for them;


Ariel is the titular character and protagonist of Disney's 1989 animated feature film The Little Mermaid and its 1992-1994 television series, 2000 sequel and 2008 prequel.

Ariel is based on the protagonist of Hans Christian Andersen's fairytale "The Little Mermaid", but was developed into a different personality for the 1989 animated film adaptation. Her distinct appearance consists of long red hair, a green tail, and a lavender seashell bra.

Ariel is a bright, spirited, and headstrong mermaid princess with a strong passion for adventure and exploration. Her tendency to explore the more mysterious depths of the ocean (or more importantly, the world beyond the ocean) can lead to an array of problems to both herself, her friends, and in the confines of her personal life - as seen when she gets into an argument with her overprotective father, King Triton. Despite this, Ariel's selflessness, compassion and intuitive way of thinking often resolve such problems, as she always takes full responsibility for her actions.
At the start of the original film, Ariel is shown to have a burning obsession with the human world, and a desire to learn more about their culture. Unlike her father at first, she views humans as aspiring creatures, astonished by their ability to constantly create, and heavily goes against the idea of them being "barbaric" and selfish as a result of this. This passion is revealed to have been prominent throughout Ariel's life years before the events of the film, as seen in the television series. By the point of the film, as seen through her lament, "Part of Your World", Ariel's obsession with the human world has reached unimaginable heights, as she spends most of her time focusing on finding, observing, and collecting various human objects that have sunk into the sea. Her obsession has also taken a toll on her emotionally, as the song begins with a sense of wonder and enchantment, ultimately climaxing in a soft end, filled with hopelessness and despair, representing Ariel's dying hopes of ever experiencing life upon the surface. These factors of desperation and despair are the prime motive behind Ariel's eventual deal with the sea witch, Urusula, to become human and experience the world above the surface. Despite not having the best relationship with her father, especially in regards to their respective views on humanity, she nonetheless was very loyal to him as well as her sisters, as after Ursula explained the deal to her, Ariel expressed some hesitance as she realized that if she succeeded in the deal (never mind if she failed her end of the bargain) she won't be able to see Triton or her sisters again, and later when Ursula cursed Triton, Ariel's first action was to attack Ursula to avenge him, even calling the Sea Witch a monster for what she did.

Ariel is also shown to be extremely compassionate and loving towards almost all living things; more so platonically than romantically. This is most notably seen through her friendship with her closest companion, Flounder, and even her father's court composer, Sebastian who, despite being against Ariel's recklessness and overly adventurous nature, is given a considerably large amount of love and respect from the princess, which is often reciprocated. With Flounder, she is comforting and patient, as well as protective, with the tendency to risk her own life for the guppies on various occasions. Her ability to befriend all various creatures, be they an abandoned killer whale, an irrationally sea creature and even the son of one of her nemesis is displayed throughout the franchise. Before she met Eric, she was rarely interested in romantic relationships, not even with any of the merman princes that Triton tried to get her to marry. The only known exception was Prince Waverly of the Pacifica Kingdom, with whom she was infatuated. However, after meeting Eric, Ariel is revealed to be a romantic, willing to make daring sacrifices for the sake of true love. Her love for him is validated by Eric's returned selflessness and sacrificial actions for the sake of love; notably seen during the climax of the film.

Like her father, Ariel has a bad temper if she ever is provoked, although hers is not as bad as his. Although spirited, even she has had some degree of self-doubts about herself, as she actually at one point considered her father might have been correct and that she may have been a freak for having any fascination for humanity. She also had a degree of seeing the good in things, as she also doubted that humans could have been pure evil from their tools and artworks.

Also, despite her usual naivety and impulsiveness, Ariel has shown on many occasions to be serious, careful, and very intuitive. One example of her occasionally showing intuitiveness was just before exploring the sunken ship, where she suggested that Flounder stay outside and be on the lookout for sharks in the area when the latter tried to fake illness.

In The Little Mermaid II: Return to the Sea, as an adult, Ariel has matured; after becoming a mother and queen of her husband's kingdom, due to the threat of Morgana at the time, she becomes very overprotective of Melody in a similar manner to how she was treated by Triton in the first film. She is shown to long for the sea, but keeps this hidden from Melody for the latter's own safety; even though it would've been easier if she had explained everything to her, she even points this out in a later scene and at the film's climax. At one point, however, she does subtly allude to her true heritage as she mentioned to Melody when sympathizing with her about not fitting in that she was "a fish out of water", with Melody not quite believing her. Regardless of her few flaws, Ariel is very much selfless, sweet-natured, and inspirational. However, her most notable trait, was her deep love and fascination for humans, having desired to become human during the events of the first film, even prior to meeting her future husband, Eric. However, she did not always have this trait; until she was 15 years of age, she expressed a deep fear of humans similar to Triton's prejudiced of humans, although her witnessing some humans saving a beached dolphin changed her views on the matter. Ironically, one of the people responsible for saving the dolphin was Eric, although she never knew it.

Melody is the main protagonist in Disney's 2000 direct-to-video feature film The Little Mermaid II: Return to the Sea, the sequel to the 1989 film in the saga. She is the daughter of Ariel and Prince Eric, and the only known grandchild of King Triton and Queen Athena.

Melody has a sassy and headstrong personality which reflects upon the personality of her mother in her younger years; but her insecurity around others and socially-awkward tendencies seem to stem more from her father. While Sebastian states that Melody is "just like her mother" in The Little Mermaid II, many similarities exist between Melody and her father, Prince Eric. Her sense of adventure, curiosity, and willingness to take risks exist in both Ariel and Prince Eric; but her mild shyness stems from a sheltered upbringing and her father's personality. Melody's curious nature leads her to collect all sorts of items from the sea, a parallel to her mother at age 16. Melody's swimming proficiency and ability to hold her breath for long periods comes from her mermaid heritage. She is also shy around boys, becoming quite flustered when a mer-boy she found attractive tried befriending her. While she also goes to the sea despite her mother telling her not to, Melody doesn't know why she isn't allowed and is against rules that make no sense or doesn't have a good purpose to follow it.
