do you know were you did the pencil lines rub out the line lightly with a clean eraser trust me i debbuged mine and took it off but debbuging can ruin your tama for ever so be careful
Remember when you rubbed the pencil lines on the debug spot?? Well if you want to risk it try to lightly erase those lines. If you don't want to risk it, I would suggest to reset your tamagotchi even though it may be upsetting.
