"Santa's Little Mermaid"
Genre: Adventure comedy
A non-swimming Santa gets rescued by a teenager mermaid whose mother faces a sushi-style end.
NIXIE, a teen mermaid, saves SANTA, who crashed with his sleigh into a lake, because his second, UNZ, fired Santa's reindeer. Santa offers Nixie his help to save her mother, captured by HESTER, a greedy hunter of endangered animal species.
Nixie's first attempt to save her mother ends as badly as Unz's to get his sleigh from the impound lot. Hester offers Nixie's mother in exchange for the painting of The Crying Mermaid, which Nixie steals and discovers its secret, the portrait carries a hidden map to the mermaid kingdom. Torn between the wish to save her mother and other mermaids, Nixie returns the painting. With Santa's help, Nixie sabotages Hester's plan to sell her mother at an evening event. A bank threatens Hester with seizing all her properties, which forces Hester to offer Nixie's mother as mermaid's sushi in a live online event. Nixie uses Unz as a fake author of The Crying Mermaid and gets the painting from which Santa erases the secret map and accompanies Nixie to Hester, who knows about the plan to the mermaid kingdom and orders her guards to catch Nixie.
Nixie escapes Hester's guards together with Santa, finds out about the mermaid's sushi event, and with her friends prepares a rescue plan which sends Hester into the hands of the FBI, Santa gets his sleigh back, and Nixie, her mother.
