Instructions
Set your sound on and keep it on for the next few days. To get Mametchi, you'll need to make sure your Tamachi doesn't drop more than one heart for 72 hours.
Starting with Tamachi at age 3, fill the heart anytime it drops. Never let it drop below one heart.
Discipline Tamachi every time he beeps at you. Never let him sleep with poo. Keep him in good health.
When he gets sick, that means he'll turn into Mametchi in the next day or two. Keep up the perfect discipline and not letting it drop below one heart and you'll have Mametchi shortly.
