Mermicorno: Starfall
A bright, serialized underwater adventure following a team of mermaid-unicorn hybrids who must band together to protect their ocean from a squid villain named Ika Inkblot, with humor, creative self-expression, and strong friendship themes woven throughout both seasons. The cutesy look draws younger eyes, but the ongoing mystery plot, themes of family separation and lost memories, and occasionally scary villain moments make it a better fit for kids who can follow a continuing story and handle low-level tension.
Comfortably suits kids around 6 to 10 who enjoy serialized fantasy adventures with funny moments and big-hearted teamwork.
Episodes to know about
The very first episode establishes that Astra's sister is missing and that Mermicornos have lost their memories of family; this emotional premise runs through the entire series and may prompt questions from younger kids about separation and memory loss.
The Ghost Town episode opens with a wailing presence presented as a scary sea spirit; revealed quickly to be a kind baby skeleton fish separated from family, but the initial setup may startle sensitive kids.
Creepy Kelp Forest is depicted as a dark, menacing environment with harrowing growls and is shown to unsettle even the villains.
