A new global craze has kids all over the world getting outdoors to play hide and seek with hand-painted rocks.
It has been praised as a cheap and easy way to get kids away from technology and outside.
The hidden rocks are typically small, flat garden stones with a simple picture or a nice message painted on either side.
The rocks are hidden in parks, with photos posted on a Facebook page so other parents can take their children to find the rocks, then re-hide them somewhere else.
The trend started in America and has spread to many different countries, including Australia.
Nine-year-old Dakota Steltman, from Pinjarra in WA's south-west, said she got the idea from her aunt in Oakleaf, Florida.
"I like the art side of it because it's fun, but it's a way to share it with the world and make other people happy," she said.
Dakota's mother, Lauri-Jane Indrelie, said it was a bit of a relief the rocks were given away.
"Dakota is art-mad and I often have to throw out some of her creations before they take over our house," she said.
Ms Indrelie said the craze taught her daughter an interesting lesson about spending time on a project only to give it away to someone else.
Rocking for a reason
A recent rock-drop on a cold winter day illustrated the motivation behind the project.
Ms Indrelie noticed a homeless man had found one of Dakota's rocks.
"He was lying on the bench, rock above his head, smiling, and I ran to my car because I burst into tears with happiness," she said.
"It's not going to change his circumstances but it's a start."
Perth woman Jacqui Larkin-Boys joined the WA Rocks group so her daughters could explore more of the country.
"The group is growing dramatically. I'd like to take it to the more rural areas rather than just being in Perth," she said.
Daughters Indyannah and Makaylah said they had not been that interested in art before they started painting rocks.
"It's fun and we get off our iPads," Makaylah said.
Rocks a solid hit online
But parents are the ones addicted to smart phones and tablets as they share their kids' creations online.
They have posted clues on social media about where rocks are hidden, as well as tips for newcomers to the game.
The WA Rocks Facebook page has attracted about 12,000 members.
The group is the largest in Australia, but new branches have popped up in eastern states.
"It is spreading. It's going to very big and we'd love to see it across all of Australia," Ms Larkin-Boys said.
