if anything happens to tama, you can always bring it back to life! To do this, when it dies, press the A and C buttons for a new egg. Once you have a new egg, press B, and you should get a screen that has 2 words on it: "Download" and "Reset". If you select "Reset" I think you get restarted. If you select "Download" you get your Tama back!
