Kids are going so crazy for Gogo's Crazy Bones that one shop owner in Gloucester is keeping them locked away.
Already, millions of packets of the little toys have been sold across the UK, and shops say they are selling out of supplies fast.
They come in lots of different colours, and you can play games with them, collect them and swap them.
But they've been banned in some schools, because teachers say they've been distracting kids too much!
Rare Gogos are under lock and key!
Paul Jennings, shop manager of The Entertainer, has locked away a set of the little toys in a safe.
He said they are so rare they're being sold on the internet for around £15-20 pounds, when they're usually sold in packs of three in shops for 99 pence!
The little figurines have been on sale since the beginning of this year, and are proving really popular.
