From Wikipedia
Hatchimals is a line of mini-figures produced by the Canadian toy company Spin Master. The flagship toys are mini-figures that feature an egg. Pressing a heart on the egg "hatches" an animal or fairy inside. When the line was introduced, the toy was a robotic animal—representing one of various species—that "hatched" itself from an egg.
