Frightened and Crying from certain toys

Oh how fun. We had a rock-n-roll elmo doll. It says "ROCK THE HOUSE!" and my son cried bloody murder. We had to put it away. Then we bought a nice toy that spits balls out the top. The motor frightened him, we had to put it away. He does not like the sound of any vaccum and we are moving, so scooting boxes across the floor has the same effect. He cries.

Peculiar. Does your baby react this way to anything?

p.s. the toy that spits the balls out, is now on the good list with Gray.
