Zoo visitors who are patient may see a new baby tree kangaroo.  Rocket is six months old and starting to pop out of his mother's pouch to explore and grab food.  He was smaller than a child's thumb when he was born in February and is now about the size of a puppy. 


He's the fifth Matshie's tree kangaroo born at the Saint Louis Zoo.
