Thousands of videos on YouTube look like versions of popular cartoons but contain disturbing and inappropriate content not suitable for children.
If you're not paying much attention, it might look like an ordinary video featuring Peppa Pig, the cheeky porcine star of her own animated series.
But soon after pressing play on this particular YouTube clip, the plot turns dark.
Parent and journalist Laura June almost immediately noticed something was not quite right as her three-year-old daughter was watching it.
In addition to Peppa Pig, there are similar videos featuring characters from the Disney movie Frozen, the Minions franchise, Doc McStuffins, Thomas the Tank Engine, and many more.
However many, like the video Laura June's daughter saw, both contain disturbing content and can pass for the real cartoons, particularly when viewed by children.
