A Norwich school has joined organisations around the world in warning parents about the challenge.
The call comes in the wake of the "Momo Challenge" a new cyberbullying game that targets young and vulnerable people online.
A WhatsApp game called the "Momo Challenge" has recently resurfaced in the United Kingdom.
Kim Kardashian warned her millions of social media followers on February 27 about the so-called "Momo challenge", which is said to encourage self-harm among children. It has been reported that the hack has made threats to kill children in their sleep and has encouraged them to self-harm.
A Norfolk school has joined others around the world in warning parents about the dangers of the internet "suicide game" Momo.
When children participate in the challenge, they contact a stranger concealing themself as "Momo" using a creepy image and communicate primarily through the Facebook-owned messaging app WhatsApp.
A form of cyber bullying that spreads through social media and smartphones, the "Momo Challenge" much like the "Blue Whale Challenge" entices users to contact a user named "Momo", after which they receive graphic threats from the questionable account and are instructed to perform a series of unsafe tasks. "We want to remind parents to always be aware of what their kids are doing on social media".
The Momo Challenge could very well be an urban myth, but if it does turn out to be real, it would truly be terrifying.

Detective Sergeant McCormill stressed to parents that any device used by children should be restricted to age suitable content, however she acknowledged media reports that the challenge had been viewed by children even with the restrictions in place.
A YouTube spokesperson has since addressed the deadly trend, writing, "Our Community Guidelines prohibit harmful and risky challenges, including promoting the Momo challenge, and we remove this content quickly when flagged to us".
It's important for you, as a parent or carer, to be present while your children are online.
Originally created by a Japanese special effects company, the character has bulging eyes, a distorted wide mouth and the body of a bird.
In another MOMO interaction a voice recording was sent to a child, telling them to use a knife on their own throat.
"As a parent, it's hard to spot these videos as the harmful content doesn't appear until partway through the video".
No one knows exactly where Momo originated, or who is behind the disturbing trend, though it was linked to at least seven phone numbers beginning with codes from Japan and multiple countries across Latin America.
