Unlike her sister Marina, Stormy is very lazy, air-headed, and somewhat selfish, much like the mermaids from the original Peter Pan film. She was originally rather rude to Jake, Izzy, Cubby, Skully, and her sister Marina. To avoid doing work, Stormy would brainwash others to do the work for her using the powerful siren song called "The Mermaid's Song", but Stormy often stays honest.
Role in the series
In the episode "The Mermaid's Song", Marina asks Stormy to complete three mer-tasks for an upcoming event. However, Stormy openly refuses but decides to do them eventually. When Marina departs, Stormy uses the Mermaid Song to brainwash the treasure-seeking Captain Hook and forces him to find seashells. She then brainwashes Mr. Smee to collect seaweed and Cubby to collect coconuts. Eventually, Stormy's brief partner-in-crime Snappy the Hermit Crab rushes off to warn Marina about her sister. When Jake (Pirate), Izzy, and Skully arrived, Marina quickly informed them of the problem but told the young pirates to clap their hands to wake both Hook, Smee, and Cubby from the spell. Marina then demands Stormy's presence and the culprit mermaid apologizes for her actions.
She returns in "Treasure of the Tides" when the mermaids decide to make Izzy an honorary mermaid. Later that night, she joins the other mermaids when they crown Izzy "Mermaid of the Year". In "Izzy's Trident Treasure", she and Marina ask Izzy for help in finding King Neptune's legendary trident. She might have a small crush on Cubby.
Stormy appears again in the episode "Cubby's Pet Problem", where she joins Jake and his crew exploring the wonders of the Never Sea when the puny pirate team in countered a baby sea serpent they've named Slink. Stormy later returns in the episode when Cubby sneaks aboard the Jolly Roger to rescue Slink from Captain Hook. She brings Slink's Mother to aid in the rescue.
Stormy attended Jake's birthday celebration with the rest of the Never Land friends in "Jake's Birthday Bash!"
Stormy and Marina make a brief cameo appearance in the episode "Captain Who?" When Captain Hook gets a whiff of the Forget-Me Flowers he forgets he is the captain of his crew. Sharky, Bones, and Mr. Smee enlist Jake and crew to help jog his memory.
Stormy returns in the episode "Izzy and the Sea-Unicorn", Izzy's new friend Cornica, a magical sea unicorn, disappears, and Jake suggests they ask the mermaids if they knew where to find her. But Queen Coralie and a few of her subjects didn't believe Izzy's tale. However, Stormy was the only one who believed Izzy's story and decided to accompany Jake and his crew to locate Cornica, who has been captured by Captain Hook.
Stormy makes a brief appearance in "Jake and the Never Land Pirates: Battle for the Book", Peter Pan comes to the mermaids' defense when a vicious sea beast enters Mermaid Lagoon.
