Now that you mention it, I really like the idea of evil mermaids. I'd like to see an evil mermaid as an icon. Think about it, an evil mermaid that sings to people and enchant them, distracting them from their work and causing them to walk off the deck or run their ships aground, squeezes the life out of drowning men while attempting to "rescue" them, or just drown men out of spite. I think Uni could pull something like this off...
