The mural to the right of the cave entrance on Sulani

I haven't, but I think it is getting close to completion.

So far this is how much is showing in my game.

I have a bit left on my mural but I like seeing how it grows more detailed :)

Hmm, well that's a wasted opportunity :(

I thought it was graffiti? I think Deligracy said it on her YT channel.

I didn't know it did anything. I got bored of the cave pretty fast. :D

I'm dying to know if it does anything. Probably does nothing and I'll just be disappointed lol.

Well it's hard to notice lol. I just spotted it by chance watching a YouTube video, never actually zoomed in that close on it while playing though. I'm guessing atleast something happens once it's "complete".

^Mine's about that too, maybe a tiny bit less far along.

I believe what @LaBlue0314 posted is as far as it gets - that is complete. And yeah - nothing happens. A lot of people, including me, thought it might be one of those secret lots - especially since there is that lighted cave looking entrance on the other side by the water where the mermaids hang out - but I and others have gone into the cave so many times and all you get is more rabbit hole options like seeing wildlife or natural wonders - they just start repeating and nothing else ever happens. Sometimes you get stuff, like kelp, and usually get a moodlet - some good, some bad.
