Charlie and Lola (2005)

Season 2: Episode 25

When Lola sees the room of Marv's brother Marty, who never throws anything away, she resolves to get rid of all of her old stuff. Charlie encourages the project, but tells her that she should recycle it instead. Later, they receive a comic called Look After Your Planet that offers a prize of a tree to plant if you're able to collect enough stuff to recycle. Charlie and Lola do their best, but find that they need some help.
