too make the happiness go up, do you just feed it snacks? if you do ur not supposed to do that you just just give it 2 snacks a day and the rest you'll hafta just play games to make it happy. Heres a little guide that i made to get a Mametchi/Mimitchi (it might not work so if it doesn't sorry!!!
Mametchi/Mimitchi - I believe it is fairly easy to get Mametchi/Mimitchi, whom is the best character you can get, care taking wise. First you must get Tamatchi/Tongaritchi (the character with legs). Than by age 6 or 7 yrs he will change. This period with Tamatchi/Tongaritchi is the most important, I believe, to getting Mametchi/Mimitchi. You will have Tamatchi from about age 3 or 4, to age 6 or 7, depending on when you hatched it. Either way it will remain in this stage for a total of 72 hours. During this time check on him about every 15-30 minutes. He will drop about one heart in this period of time. As soon as he does drop 1 empty heart, fill it right away. Don't let him drop below one empty heart, or your chances of getting Mametchi/Mimitchi is at risk.
Best thing to do is either really keep an eye on the attention icon, or always keep the sound on. He will beep at you for attention and for no reason. He will have dropped one heart, and need discipline. You can't play or feed him meals. So discipline him then take care of him. Discipline him every time he calls for it. This will be a total of 2 times after he has legs. If you disciplined him all the way in the Marutchi/Tonmarutchi stage, the discipline will start off as 50% in this stage. After the finale time you discipline him he will get sick soon after. Also him getting sick tells you that he will change within the next 30 hours. Usually the very next day after being sick. Overall, you need to take as perfect care as possible to get Mametchi/Mimitchi. If you slip and miss a discipline, let the hearts drop below one empty one too many times, or let him sleep with poop next to his bed, your chances of getting a Mametchi/Mimitchi is at even MORE risk.
