Hi,your tamagotchi needs to be an adut, needs a merror, and, most of all, needs make up. I got my merror from a GENNILAMP.
Merrors are 1400$. How do I know? I see a merror in my shop all the time! You can use the merror as many times as you like. You can only use the make up once. If you want good luck on getting a merror, always buy a GEENILAMP or save up points.
I'm li'l tama lover#1!!! and I'm wishing you good luck on getting a merror!
P.S. If u see a merror in ur shop, it kind of looks like a circle on a desk.
P.P.S. Hope I helped.
