There is how you get Mametchi. Mametchi is a PERFECT care Tamagotchi, but it isn't that hard to get perfect care. ^_^
1. When you're Tamagotchi is a Teen, boy. You have to give it 4 happiness, and Hungry heart all the time.
2. You have to make you're Tamagotchi go to the toilet ONCE ot more. Even if he poops, LOL, You still have to clean it up as fast as you can!
3. Play with you're Tamagotchi sometimes, in games or in it's band!
Tip: If you don't want to care for you're Tamagotchi sometimes, put you're Tamagotchi on it's sleep time. Then it's easier to get PERFECT care that way! But you have to let it go to the toilet or poop. If you don't, it will get a lower care.
