Apparently the Furby Booms have a name that's inaccessible on the Connects.
Tay-Tah = Fire Weasel
Here's a theory on why you can't name your Connect this.
So, there was supposed to be 130 names, but they cut out one of them.
I was looking everywhere for a place that has all the Furby Connect names and translations in text form and I didn't find anything, so I decided to post them myself.
Here they are, all 129 of 'em:
Ah-Bay = Happy Snuggler
Ah-Boh = Sugar Beach
Ah-Boo = Bear Hug
Ah-Dah = Bubble Bath...
