Sometime ago, King Poseidon's wife was killed by pirates in the seas. Since then, King Poseidon had been craving for revenge on the pirates. One day, he uses his daughter, Ursula, to lure Captain Hook and his crew so that he could kill them. This however backfired as Ursula wishes no harm to the pirates. She then steals a magic bracelet from the King to walk on land. She then begins singing at a pub to earn gold to travel to Glowerhaven. Her singing caught the attention of Captain Hook and offers her a ride to Glowerhaven. After finding out that Hook plans to take his daughter, the King makes a deal with Hook, trap Ursula's singing voice in an enchanted shell for squid ink. At first, he declines, but later, in order to hurt the King, Hook takes Ursula's singing voice. Angered by the betrayal of Hook and her father's actions, she takes her father's trident and turned herself into a powerful Sea Witch, taking over the realm from her father.

She gives Ariel a magical bracelet which can give legs forever, but someone else would have to take her place as a mermaid. She then gives it to Snow so that she could use the mermaid magic and travel far away from the Evil Queen. The Evil Queen then interrupts them, claiming that she was never the true Goddess and had trapped Snow. Ariel then stabs the Queen's neck with a fork and removes the bracelet from Snow's wrist and escapes together.
