I tested my pink RB when I had the noon clock battery problem, but now I was playing with my Pleo during her sleep time. I turned her on and she was OK and played a while, but as soon as I ignored her, she shut off and gave me one beep. I know this is the sleep clock. I tried to pet her and she did not wake up. Is this normal? She is not making any sounds like she is sleeping. I did not pull her battery. Is she supposed to wake up on her own ....in about 2 hours? Thanks! I have never tried this before.
