I didn't have toy myself when I was a kid, but I remember something that this girl had when she was a toddler. It was a cleaning vacuum, with which a child do cleaning.
So, to use this toy, first she'd turn over the plastic bag that has "dusts" (toy dusts).
Then she'd use the vacuum to clean there.
And repeat this like forever;
It kinda got to my nerve... xD But just because wanting to see this cute butt of hers - that's covered with knit pants for toddlers, I'd always let her enjoy "cleaning".
