I have a teenage apple-looking tamagotchi v2 that will only play games if he is not at his base weight. He will accept up to two meals at a given time. The only way I can seem to get him to play any games is if I feed him at least a couple of snacks first. Is it just the tamagotchi I have or is this the case with all of them? I only have two bars of training. Does that make a difference? Thanks!
