Manic Mermaid is the mermaid guest character in Xilam's animated series Zig & Sharko.
Manic Mermaid moves to the same lagoon as Marina. Marina does not like that and they have a small war between themselves. Zig the hyena tries to take advantage of it but ultimately still fails to get any mermaid to eat.
Manic Mermaid was later seen by King Neptune's arm going into the opera.
