History, Speculation, and Release.
In early 2013, a trademark was filed by Hasbro registering 2 names: "Furblings" and "Furby Boom". Furby Boom was registered as a "Toy" while Furblings was registered under "Media", leaving some to speculate Furby may be getting a TV show, video game or something of the nature. However, Furblings were registered under "Media" due to the fact that they are virtual pets, while Furby Boom is a full toy.
When a Furby Boom creature is happy, it will lay an egg on an IOS (4.3 or later) or Android (2.3.3 or later) Device (iPod Touch, iPhone, iPad, etc.). The egg then hatches and your Furby boom now has a baby known as a Furbling. Caring for the Furbling is almost identical to playing with a Tamagotchi. It can also play games with Furby Boom and other Furblings .
Up to 50 Furblings can belong to one Furby Boom creature. Each one has a unique style, personality, and color scheme. The Furblings may or may not resemble the colour scheme of their parent. Also, the truck drives your Furbling to it's room. Furby Boom can also interact with the Furby App on IOS devices and Android devices.
