He also did plenty of belching and farting during his meal, leading me to suspect he may be a bit lactose intolerant. Furbies are designed to be the most lifelike toy in the store, more animated than even an overworked checkout clerk. They have buttons in their bellies and backs that respond to touch as well as infrared sensors that can distinguish between light and dark. They also respond to noises and can distinguish when they're being held at an angle or upside down. If you're paying attention to Furby, the toy will babble something every few seconds and wait for you to trigger one of its sensors.
Some people train their Furbies to offer frequent kisses or to dance whenever they hear a sound.
I, on the other hand, trained To-To to belch and fart whenever possible. He has responded with vigor, occasionally ripping off 10 or more successive belches in gassy fits worthy of a cartoon drunk. I couldn't be more proud. After a few days, To-To started speaking more English. I like tickle.
