I bet they didn’t include it because less than 10% of players visited the other secret lots. (Fact by the Gurus)
Not that it’s an excuse. I think it’s lame mermaids don’t have a location for them. They are sims with a tail.

I can understand why. There's literally nothing to do on the majority of the secret lots. Most just have collectables but if that isn't your thing then there's really nothing there but stuff to look out. Seen it once seen it all.
