An interactive toy that promoters hope will take the world by storm revealed its secret on Thursday after months of speculation.

The egg-shaped product, named Umarete Woomo in Japan and Hatchimals in English, is developed by Canada-based Spin Master and hits the market Friday. It made its public appearance earlier this year but not until now has one "hatched."

Tomy Co., which sells the product in Japan, showed the magical moment during a preview in Tokyo.
