I'll check for that spots .

She has never ever made sounds at night. Dino has been doing them sounds almost every night and day(some times) since he was half of chum chums size.
When I first got chum chum I where told it was male so I didn't put much attention to it. I always had a feeling chum chum is a female. She is also younger than Dino but just a bit larger than he is.
