’Mystery black mark’ on $27 toy leaves Kmart mums baffled

A $27 doll has sparked an online investigation after a mum turned to Facebook asking for help identifying this blemish. Do you know what it is?

A concerned mother has sparked a social media storm after sharing a photo of a “mystery black mark” that has appeared on her daughter’s Kmart doll.

The strange blemish appeared on the back of the toy’s head with seemingly no explanation as to how it got there.

After turning to the internet for help identifying what could have caused the mark, the mum was encouraged to conduct a full-scale investigation that included cutting into the doll’s head.

However, the woman and the 380,000 members of the Kmart fan group she posted in are still no closer to identifying the mark.

Can you help solve the mystery?

The bizarre chain of events began when the stumped mum took to Kmart Hacks & Decor to ask for help.

“Does anyone have this doll? We’ve had a random black mark appear on the back of the head (definitely not pen/paint etc),” she wrote in the Facebook page.

“Am wondering if it’s a burn mark and something wrong with the mechanism inside that makes the doll ‘talk’.

“It started out fairly small but has gradually got bigger. No smells or anything from it.”

Her concern was so great, she admitted she was “contemplating cutting it open to take a better look”, in case the mark was a sign of something sinister inside.

Hundreds of Facebook users responded, equally as concerned as to what the mark could be.

“This is pretty scary. Mould or burn marks .... either way, not good. Eager to hear the outcome,” one mum wrote.

“I cut one open years ago for this reason and found it to be full of mould. Quite concerning!” another added.

Many implored the woman to “perform surgery” on the doll in a bid to solve the mystery.

“I have never been so invested in a story about a doll before, but at the same time have a strange eagerness to want to see her head cut open,” one person admitted.

“Cut it open already, the suspense is killing me,” another agreed.

While one quipped: “This post has been more intriguing than watching Netflix!”

Eventually the mum updated the group, revealing she’d “cut it open” but was “still not sure” what the black mark was.

“The mark doesn’t budge when cleaned, definitely doesn’t look like mould either so [it is] still a mystery!” she said.

She went on to say she’d ruled out as many possibilities as she could, but was still utterly baffled.

“My little one hasn’t dragged it on the floors but has thrown it around a fair bit. Possibly left in direct sunlight? I’m as puzzled as the rest of you!”
