A grieving mother who lost her six-year-old son to cancer, is hiding Hot Wheels cars, her little one's favourite toy, around their Indiana neighbourhood to help honour his memory.
And, the family is asking the community to let them know when they discover the "Finders Keepers" bags, which also contain information about childhood cancer and links to help raise much-needed funds.
In June 2015, Tracey Blackmore's healthy and happy boy, Brooks Blackmore, was diagnosed with two stage IV inoperable brain tumours. He underwent six weeks of radiation and monthly oral chemotherapy.
"We were told there was no cure," Ms Blackmore told Essential Kids, "and he was given a very poor prognosis." During this time Brooks lost all ability to eat on his own, talk, walk and sit up.
Much to their - and their doctors' - surprise, however, his condition began to slowly improve.
"We were experiencing a miracle," Ms Blackmore said. "[Brooks'] brain tumours were starting to shrink and doctors told us they had never seen this tumour shrink so much in such a short period of time. We had no doubt he was going to beat this nasty tumour."
Their happiness, however, was short-lived. "Out of the blue", in March 2016, doctors found a tumour on Brooks' cervical spine - one that was too aggressive and resistant to radiation.
"He did everything he was asked to do," Ms Blackmore says, adding that her little boy "fought so bravely."
Only weeks later, on May 21, Brooks lost his battle with the disease. "Our hearts were broken," Ms Blackmore says. "He was brave to the end and inspired thousands along the way to be bigger than brave, to 'Be Brooks Brave' and live in the moment."
To help them through their grief and to raise much-needed funds for childhood cancer research, Brooks' family created special bags containing Hot Wheels cards donated by Mattel. Labelled "Finders Keepers, #BeBrooksBrave" the bags, which have been hidden around Indiana, also contain Brooks' story, a copy of his painting and a link to his St Baldrick's Foundation fundraising page.
The 200-plus cars have been hidden in some of Brooks' favourite places: Target, his old preschool, the Chick-fil-A play area, McDonald's, local primary schools, and Panera, his favourite restaurant.
"Brooks has always had a love and passion for collecting and playing with Hot Wheels," Ms Blackmore said, describing that her little boy even had a Hot Wheels themed third birthday party.
"We have so many special memories of Brooks playing with the cars in every room in our home," she said. " He hardly left home without one."
The toys also brought Brooks comfort while he was undergoing cancer treatment. "One of the only things he could do was hold and manipulate his Hot Wheels," Ms Blackmore explained. "It gave him such joy to receive them as gifts," she added, describing that they would go out and choose a new one 4-5 times each week.
It's a tradition Ms Blackmore has continued, even after her son's death. "I still buy one for him every week and drop it off at his grave site," she said. "I am sure to line them up in perfect row ... just like he used to."
The idea for the special bags came after the family visited Legoland in honour of the Make-A-Wish trip Brooks was never able to enjoy. "We decided to leave a few "Brooksy" Hot Wheels around Legoland and San Diego," she said, "just to give us comfort and to know he was with us."
A friend shared their story with Mattel who were so touched they sent the Blackmores three boxes of brand new Hot Wheels cars.
"I knew I needed to so something big with them to honor Brooks," she said, "and to spread kindness."
Ms Blackmore's wish is that one day Hot Wheels will make a special Gold car for Childhood cancer. "My dream is to have it named after Brooks," she said, "and all proceeds would go to St Baldrick's Foundation."
Thus far, $18,050 has been raised in Brooks' name - surpassing their initial goal of $10,000.
The Hot Wheels project is helping the family as they prepare to face a tough few weeks ahead. Along with their first Christmas and New Year's without Brooks, December 20 would have been the little one's seventh birthday. Ms Blackmore also turns 40 on 16 December - and will celebrate her younger brother's wedding in early January.
"I didn't want to sit around and feel sorry for myself," she explained. "I wanted to spread Brooks' love and his story in order to feel him near me. I feel closest to him when I am happy."
Ms Blackmore is also passionate about raising awareness and money for childhood cancer. "No family should ever have to hear the words "incurable cancer", she said.
"Knowing that Brooks' name and story still inspires others around the world, is helping heal this mama's broken heart," Ms Blackmore continued. " He is not forgotten. We need more love in this world and I truly believe that Brooks is helping change the world that knows him."
