The stuff inside the screen is either LCD (liquid crystal display) or LED (Light emmiting diodes) Because i opened mine up because it brokes and there were rubbery things and when i put 2 batteries on it, the screem lit up
i agree with tamamum just watch a pattern for when it is smiling or something else that means its is happy. i usually get 270 p-900 in about 10 minutes
I know id be angry if my tama got eaten but still, shooting my dog would not bet the appropriate thing to do! A dog is a dumb animal that can't tell the difference between a tama and pork liver treats! Calm down a little!
