He told me the red one was really really tall, with long arms and long legs, and long fingernails, and a long neck. He blue one is really small, with a small face and small knees, and small feet and small arms. The green one is big, just like the red one, and the yellow one is a tiny tiny baby monster.
I told Kai these monsters sound a lot like our family, the red and green ones are the mommy and daddy, the blue one is a little boy monster just like you, and the yellow one is a baby, just like the baby in mommy's tummy. I told him that I bet they were not trying to be scary at all, they probably just wanted to be friends.
So, he sat there for a minute and thought about it and then he said.... But mommy, I forgot to tell you about the gorillas.
It was such a cute story... I just had to share.
