Speedy has! She's so small, it was very hard to find her! One day, when we first bought the playpen, I was getting Perrie out and my sister went to get something, leaving Speedy unsupervised.
Well, turned out there was a hole in the playpen, big enough for her to squeeze through. Guess who had to look for her? Well I eventually found her under the couch.

Boy did that sister of mine get a lotta scoldin'!
