The little dog..that thinks it is a big dog...

Penny is a little dog that thinks it is a big dog.  She copies whatever her older siblings do, and says whatever they say.  She tries to sit on the toilet, get on a bike, eat a chicken leg, call people on the phone ("he-whohw!), take toys and say, "MINE!", bark orders at poor Sam, do all the hand motions to every VBS song, after watching the kids do them, run around with all the big kids, jump on the trampoline, jump into the big pool, snap, clap and dance like a FREAK, wave hello and goodbye to all visitors, parents, and neighbors, preferring a specific pair of shoes, eating a single scoop from Rite Aid, and a multitude of other crazy things.
