A Belfast school has issued a warning to parents after pupils as young as Primary One had been watching videos including a character called Huggy Wuggy.
The dangerous videos have been accessible to kids through YouTube and TikTok and show a razor-toothed character which is part of a horror game.
The trend has been worrying parents whose children have been seen mimicking clips from the game in the school playground, which includes the scary creature singing about "hugging and killing" and asking viewers to "take their last breath".
