Elliott likes to test the boundries of how far he can go before Mommy goes chasing after him.
Its hard to tell, but Elliott is slapping his legs to the beat of the music. When a song ends, Elliott is very good about clapping to show his appreciation and says "Yea!" Elliott finds a friend to help him beat on the windows of the toy store. "Open up! We know you're in there!" Mommy attempts to discourage window beating.
Elliott is an excellent audience. He tries to get Mommy to help him play the musician's drum, but Mommy refuses. He resigns himself to dancing instead.
Elliott holds a gumball from a Sweet Gum tree. Mommy found it for him, but he is unimpressed. He instead goes back to trying to climb the steps of storefronts.
