Well here they come :D
This girl is a little taller than her sister. She Loves to dress up and wears a Blue bell dress. Notice the leafs at her neck. She delights in doing hand stands on the blue bell stems and her yellow stockings make it so she blends in perfectly.
So.... when you hear that fainting tinkling when you walk by the blue bell patch followed by what you think is a tiny dainty giggle. It very likely could be this little darling.
