Furby
Book Furbies were also released, including an interactive Furby-like Gizmo, from the movie Gremlins, a Furby-like  Interactive Yoda based on the Star Wars character, and a Furby-like Interactive E.T. from the movie of the same name. Another 'friend of furby', called Shelby, is similar to Furby, but looks like a clam, has lots of improvement in memory, and has a different personality; it was released in 2001 and can communicate with the original Furbies and Furby Babies. They also have sensors that can sense loud sounds, they can sense being upside down (they say things like "Shiver me timbers" and "Walk the plank", in the style of a pirate ship captain, when you leave them upside-down for a long period of time), and they laugh when you "tickle" them (their antennae - or "tennies", as they like to call them). They also purr when you "pet" them. You can feed them by sticking your finger in their mouth. Similarly, Shelbys do not have their own names, unlike the classic Furbies. Shelbys are also capable of knowing if it is talking to a Furby or another Shelby, saying phrases such as "Where's Furby?" - though they cannot tell the difference between a Furby and a Furby Baby - they just think it's a Furby. In addition to English, Shelbys also know some Furbish words and also have their own language called "Shelbish."
