This particular treat ball was given to me by a friend. The voice recorded within is that of her ex mother-in-law, who is a unique person in that she's a series of DSM-IV codes. I won't go into it. However, the sound that issues from the ball is a breathy high woman's voice, pleading with you.
The final effect is similar to that of the glowing-pulsating-red-heart ghost bride at Disneyland's Haunted House, calling you back, back, back to the grave.
I had it around the house for a couple years at least. It was on a little used desk but sometimes I bumped it and the voice came out. A couple of times it went off unexpectedly, which was a treat. My cat just looks at me funny when it makes noise.
Recently I put it in my car's trunk. I am not sure why; maybe I meant to take it to someone's house and make them afraid. Anyway, I would hear it when I braked or took a hard turn, or went over a bump. For a while I didn't realize what the sound was and kept thinking it was the stereo or maybe my phone having pocketdialed someone. I found it in the trunk again today and thought I should remove it because constant use would run down a battery.
Anyway I camvideo'd it:
