Parents everywhere should be aware of the new scam that is affecting YouTube children's content.
Thousands of videos have been produced which are posing as classic kids cartoons, like Peppa Pig and Doc McStuffins, but are actually gruesome and disturbing clips.
Some of the videos can be accessed through the YouTube Kids app, which is supposed to filter out inappropriate videos before kids can see them.
One video, posing as Peppa Pig, shows a dentist with a large syringe pulling out Peppa's teeth as she violently screams in distress.
Laura June, a journalist, stumbled across some of these videos when her 3-year-old daughter came across it.
"Peppa does a lot of screaming and crying and the dentist is just a bit sadistic and it's just way, way off what a three-year-old should watch," she said. "But the animation is close enough to looking like Peppa - it's crude but it's close enough that my daughter was like "This is Peppa Pig."'
Another 'Peppa Pig' video shows Peppa deliberately burning down a house while someone is in it.
There are hundreds of these videos currently online, with copy-cat animation of popular shows like Frozen, the Minions franchise, Doc McStuffins, Thomas the Tank Engine, and more.
The videos often show up on the "recommended video" section after legitimate cartoon shows, so it's easily accessible to kids who are browsing. The clips are often named the same thing as the shows, but it's clear the animation is off.
Social psychologist Sonia Livingstone, says this is a good opportunity to talk to your kids about online safety.
"It's perfectly legitimate for a parent to believe that something called Peppa Pig is going to be Peppa Pig," she told the BBC. "And I think many of them have come to trust YouTube... as a way of entertaining your child for ten minutes while the parent makes a phone call. I think if it wants to be a trusted brand then parents should know that protection is in place."
YouTube claims that any videos that don't belong on the app are "removed within hours." But with hundreds of videos showing up all the time, it's important to make sure you know what your kids are viewing.
