Some pesky rats snuck into her bedroom one night and stole all her clothes, thus this poor girl was forced to spend her entire day naked. Humiliated, she darted about her town in search of something that would solve her problem, and that's when she found just the thing: an empty cardboard box.

So she cut a rectangular hole in the front, so she can see; her prized white hairbow on the top, so people were aware she was a girl; and drew a big, wide smile just below the hole with black marker, so anyone would see her wouldn't be frightened. And just like that, the Box-Girl was born!

And as for her stolen clothes? Sadly, she never found them. But she eventually came to like her new "attire" that was the cardboard so much, she frowned upon clothes entirely and started wearing the thing 24/7. Thus, this was the girl's life now: exploring the world around her, wearing nothing more than an empty carboard box.
