Jak and the Magic Nano-beans: A Graphic Novel

Mom wants Jak to sell Cow for scrap, but Cow and Jak have become best friends. So instead of selling the rusty old robot for spare change, Jak strikes a bargain with the scrap collector: if Jak and Cow can visit the Cloud Kingdom via the Space Elevator and get hold of some magic nano-beans, Jak can keep Cow safe and sound.
