Yumel

can be programmed to go to bed and wake up at specific times of a day and you as a owner can let it know when you go to bed and wake up by touching it. If you go to bed or wake up at irregular times, Yumemi detects it and says things like "Are you alright?" or "You work too hard, don't you?" (Yumel can actually say 1,200 different phrases in response to touch and sound.)

It's interesting, but I don't know if I want a toy asking to me if I'm fine just because I like to sleep in strange hours. (via Popgadget)
