A robot toy, which giggles when tickled and which was originally designed to help autistic kids learn to interact, is now selling like hot cakes both in America and Britain ahead of Christmas.
The bright yellow robot toy -- named "My Keepon" -- keeps perfect time to any style of music. The Sun said. It reacts and picks up any music beat.
It is manufactured by Wow! Stuff in Britain's Wolverhampton city.
The robot toy became an internet phenomenon after almost three million people viewed a video of it dancing to a rock music track.
Ahead of Christmas, stocks have sold out and sellers are offering the 40 pound (around $63) toy online for five times the normal price.
