Police in the U.K. have warned parents about a killer teddy bear called "Huggy Wuggy," who has been appearing in videos online.

Children as young as five are being traumatized and acting out after seeing clips of the character on TikTok and YouTube.

The terrifying videos have been slipping through safety barriers on the internet due to their innocent titles. They show "Huggy Wuggy," the character from a horror game with razor-sharp teeth, singing about "hugging and killing."

The disturbing clips are prompting young children to mimic his actions in school playgrounds by hugging and whispering "nasty things" into the recipient's ear, according to 7NEWS Australia.

"We are seeing children recreating a game on the playground with hugging and whispering nasty things," Justine Brown, the headteacher of a primary school in Kent, said, as per the outlet. "It is a very deceiving character, as hugs should be seen as something kind and loving, and because of its cute name, it can infiltrate firewalls and filters. Please be vigilant about what your children are watching."

Parents have been warned by the police about "Huggy Wuggy" popping up on social media and asking young viewers to take "take their last breath."

"Set in an abandoned toy factory, Huggy is a villain in the game who stalks the players from vents are unreachable places. Videos of the game are available to watch on YouTube, with other clips dedicated to Huggy in songs," a Dorset Police spokesperson said, according to Dorset Live. "One song includes the lyrics 'I could hug you here forever, till you breathe your last breath together.'"

The clips on YouTube and TikTok include "videos" and "songs people have made" using graphic imagery of the blue bear-like character, Chris Conroy, a cyber protection officer for Dorset Police, said, as per the outlet.

"It's based around jump scares and things you certainly wouldn't want children exposed to," he added.

"If you were to use even YouTube kids, for example, it may slip through because there is nothing obviously sinister about the name of a video," Conroy went on to say. "It really comes down to paying attention to what your children are doing and making sure they are not just trusting YouTube Kids videos are safe because unfortunately with videos like this, things do slip through the cracks."

Rhia Fearn, a 35-year-old woman with two children, admitted that she thought "Huggy Wuggy" was an innocent character because of his name but was shocked when her 5-year-old son, Harrison, described him as someone who kills people.

"I was asking him questions about whether he was a goodie, and Harrison was adamant 'no, he's a baddie and he kills people,'" Dorser Live quoted her as saying. "That was really contradictory for me because I thought 'that can't be right — he's called Huggy Wuggy.'"

Fearn is concerned about the worrying trend, which has "infiltrated" her child's mind without her being aware of it.

"It's really frightening as a lot of parents will be oblivious to this level of violence our children are being exposed to," Fearn added.
