Playing in the Toy Box

We got this toy box for Cheyenne's new room but we haven't gotten it ready yet. It's still got the queen bed in it. So until we get it ready, the toy box has been in our room. Last night when I was folding laundry, Chey decided to crawl in the toy box to play. She thought it was the funniest thing. She stayed in there for the longest time. When the box gets full, she won't be able to do that...unless she pulls all the toys out first. Now what kind of toddler would do that?!?
