A school has issued an urgent warning to parents as young pupils have been watching videos featuring a character called Huggy Wuggy from a horror game and then mimicking the clips.
One Belfast school said children have been accessing the upsetting videos, which feature a razor-toothed monster from the video game Poppy Playtime, through YouTube and TikTok.
One clip shows the creepy Huggy Wuggy singing about "hugging and killing" and asking viewers to "take their last breath" - and it's worrying parents whose children have been copying the video while in the school playground, reports Belfast Live.
Cregagh Primary School in East Belfast warned parents of the trend and asked them to be vigilant around what children are watching.
In a post on the school's Facebook page, principal David Hegarty said: "It has been brought to my attention that a character named 'Huggy Wuggy' is being viewed by our children online, some as young as Primary One.
"The character can be easily viewed on YouTube channels and is a teddy bear with razor sharp teeth that sings worrying songs about hugging and killing.
"On one of the videos the bear asks the viewer to take their last breath.
"It is a very deceiving characters, as hugs should be seen as something kind and loving, and because of its name is able to infiltrate firewalls and filters.
"I just wanted to inform parents so you are aware and can be vigilant around what your children could be watching."
The same post was also shared to the Facebook page of Abbot's Cross Primary School in Newtownabbey.
One mum told Sky News her three-year-old son tried to jump out a window believing he'd die and come back to life "like Huggy Wuggy does" after watching the creepy videos.
