You got 4 series of dolls. Doing the Minimoni hail, doing the ainn, the Doll Festival and the Strawberry Pie.
When the group was joined, Yaguchi was 17 years old, Mika 16, Tsuji 13 and Aibon 12, so yes, the girls were so young (and Marippe soooooo cute, even in Mini Moni she was the tiniest )
I envy your colection, maybe some day...
