Why doesn't he talk... and a million other questions

So Larry-Boy was at the store today.
We went and Gavin clung to Mandy for dear life when Larry-boy came out...
He was scared. But the funniest part was when we got home.
Gavin had a million questions as to:
Why does he have arms?
Why wouldn't he talk?
Why couldn't he use his ears to fly?

My goodness....
Good thing he didn't know that the video has a counter top as a back drop thus Larry is only 4 inches high.... So how does he get so tall?
