Mum-of-four, Jessica Mags, bought her kids a cute cuddly stuffed toy.
It was a unicorn; every child's fascination.
So when Mum brought the cuddly toy into the house, she knew straight away the four kids would go crazy for the little thing.
But this mum was a little more prepped and sneaky than the rest of us, because this wasn't any ordinary toy and she knew it.
Showing us a clip of the unicorn, it looks as cute as a button, until Mum presses a button and within seconds we're terrified.
In a hilarious clip posted online, Jessica shares the moment her son saw the toy and what actually happens.
His reaction? Priceless.
However, Jessica does point out that her son isn't traumatised and in fact, loved the video so much he couldn't stop looking at it.
So funny! Let us know what you think of the prank...
