I saw these at a Suncoast video, with an LCD display that shows a character's face and a button on the side to hear that character tell you what time it is. The one I tried had Cartman, and the time I got was around one o'clock, so he finished with a feeble cry of "I'm so hungry!"
How many different voice samples are on these, other than the time? Something specific for morning, afternoon and night only or something different every hour?
