This little boy hasn't come into the story yet. He'll be in the stories soon. He'll also have stories of his own.
Ari is the gentle giant. He was born a big boy: he started getting big and just didn't stop.
Ari thinks everything he says and does is funny, so he does it again and again to make you laugh...again and again.
He's the best at annoying his brother and sister with whatever they're doing. He's good at copying his sister at karate practice.
Ari watches the same movie over and over. He also repeats things over and over until he gets the attention he wants.
