Morgana's Ice Cave is an icy cave in the Arctic, home to the sea witch Morgana, the main antagonist of the direct-to-video animated feature The Little Mermaid II: Return to the Sea.
Morgana always plans and plots within her cave where she calls home. Her sidekicks' Undertow, along with Cloak and Dagger, also live there.
Melody, daughter of Ariel and Eric, was led to the sea witch Morgana by her evil sidekick Undertow so she can ask her for her help, having been told by Undertow that Morgana has great magic powers. It was there that Morgana turned Melody into a mermaid for one day but temporarily as part of her plan to manipulate the young girl to steal the trident that belonged to her grandfather, the sea king Triton of Atlantica.
After successfully tricking Melody into giving her the trident, Morgana (after she was diguising herself as Patricia) rose out of her ice cave and declared herself queen and ruler of the seas. She then magically transformed her cave into a huge icy palace with the trident, while all those who tried to resist her were subdued, including Prince Eric and King Triton. Melody, however, successfully retrieved the trident back from her and returned it to her grandfather, Triton, who imprisoned Morgana in a block of ice, which then sunk to the bottom of the ocean while her ice palace crumbled and collapsed.
