And it takes plenty of green to buy one.
But the snakes come in a variety of colors, which has inspired breeders and collectors.
The pricey pythons typically sell in the $1,000-$5,000 range.
But unusual snakes go for more than 10-grand.
Green tree pythons can have spots and patterns of yellow, white and blue.
Longtime breeder Tim Morris, a Maryland schoolteacher, is credited with creating the first all-blue green-tree python.
But Morris says even having blue parents doesn't guarantee a blue baby snake.
He adds you can't tell the adult color of a green-tree python until the snake is about a year old.
