hatch daySpin Master Corp. will unveil Hatchimals on Oct. 7, where consumers will be able to see and purchase the toy line for the first time at major retailers and on spinmaster.com.

Hatchimals integrate the company’s technology to bridge multiple play patterns. So far, Spin Master has only revealed the toy’s egg-shaped exterior publicly. Kids will be able to select the color and species of the Hatchimal egg, but what’s inside will only be revealed by holding and hatching the egg.
