Just for those who don't want to explore and find these quickly. For those who want to help, please put down any coordinates or islands with said statues!
You'll find them easily as they shine like artifacts/message in a bottle and play loud music.
Locations [ Statues have random spawns, but these are still possible locations. Not sure how the spawning works, I've only played one hour of the new event, so my apologises! ] -

Mermaid's Hideaway - B16
Lagoon fo Whispers - D15
Crooks Hollow - Q19
Crooked Mast - T13 - NE side, under the water. Saphire.
Update: I guess they are randomized! That's neat, makes them a bit more "tricky" to find them, but so far, they've been relatively easy to come by. Good luck to everyone!
