A new toy on the market is quickly becoming a parent and child's worst nightmare.

The cute, bright little balls called Bunchems promise hours of fun for the kids. What happens in actuality is hours of pure misery for parents and children as they try to detangle them from hair.

It's such a problem that there are YouTube videos explaining the best way to remove the little 'orbs from hell.'

So when your child screams for Bunchems this Christmas, take the sound advice of parents who have lived through this nightmare: just say no!
