Video killed the radio star

I was on Sirius radio again playing a game! I called in on my drive home from work. But unfortunately, unlike when I called in last October, I was not a winner. I answered three questions correct, but got the fourth one wrong :( The game was asked questions about babies - but I lost on this question:

Q: What is a Musty? A. a bottle B. a stroller C. a crib D. a stuffed animal

A: a stroller.

I didn't know - so I guess a stuffed animal. Apparently the stollers are big among the celebrity set.
