The Hammerhead Shark is a minor villain from The Little Mermaid II: Return to the Sea.
The Little Mermaid II: Return to the Sea
This shark appeared when a baby penguin is hanging for her life and the others are trying to save her. Soon when Tip and Dash came in, the ice fell down on the shark's head. The shark is completely crushed by falling ice, but it could be presumed the shark survived. This could be because the shark was frozen when crushed by ice.
