What if they replaced the zoo with something else cool? Like a Moonbase or underwater Cove?

Just thinking out loud here… I know many of us are sad about the zoo going away. I wonder if it's simply the same resources or if they're planning on putting something else in it's instead

I was trying to daydream about what that might be and I thought how pretty it would be if they did like an underwater Cove where you unlocked coral reef or mermaid habitat or… IDK… Something fun that you could also work towards and collect

What do you think? What would you like to see them replace the zoo with?
