Mr Grumpy, Mr Happy and Little Miss Naughty are about to make appearances throughout Rotorua parks and reserves.
They are Sonia Foote's latest "art rock" babies which she will soon set free into the world, and wait to see who the lucky finders are.
It's all part of a craze which is sweeping the country - Rotorua Rocks (#RotoRocks) is the local answer to an art-rock treasure-hunt-type, non-digital trend replacing the likes of Pokemon GO.
Ms Foote from Facebook group Rotorua Rocks sums up the concept in one of her posts.
"Rotorua Rocks is all about spreading a little happiness, making memories and uplifting others. Post in this group to show us your rocks when you've painted them, let us know where you're going to hide them, show us a rock that you've found, say where you've re-hidden a rock that you've found or anything else rock-related."
