The Mermaid mouse is an incredibly shy breed that avoids hunters as well as other mice. Its timid nature makes it incredibly rare and hard to find.My catch: I was successful in my hunt! I caught a 1 oz. Mermaid mouse from the S.S. Huntington II worth 2,400 points and 601 gold. It's hard to argue, but it's my first encounter and catch of the Mermaid. I was using the Aqua Base.. (and Partybot with Swiss)..
