Hatchimals

Hatchimals is a line of mini-figures produced by Spin Master. The flagship toys are mini-figures that feature an egg, in which you press your finger on the heart of the egg to "hatch" the animal/fairy inside. When the line was introduced, the toy was a robotic animal—representing one of various species—that "hatch" themselves from an egg.

After their initial release in October 2016, the toys faced an unexpectedly high demand. Media outlets expected them to be the top seller of the holiday season, leading to raffles and waiting lists over the limited stock, and comparisons to other major toy phenomena such as Cabbage Patch Kids and Tickle Me Elmo.
