You can't turn your tama off, but you can pause it. If your tama not an adult it slows down the life cycle though. To pause it you hold down A and B. You do the same to un-pause it.
Sorry, there isnt a way to sttop the battery from running out.... sorry!! But as some people have said, you can always pause your tama so then you dont have to look after it 24/7!
:furawatchi: well in my head if you pause it, its growing progess will stop and if you take the batteries out then mabe ur tama will start over.and if you put the plug in it might die or restart
what i do is turn off the lights so i feel like its off
