Jak and the Magic Nano-Beans

Jack and her robotic servant, Cow, are in a pickle. Mom wants Jak to sell Cow for scrap, but Cow and Jak are best friends. Instead of selling the rusty robot for spare change, Jak strikes a bargain with the scrap man: if Jak and Cow can visit the Cloud Kingdom via the Space Elevator and get hold of some nano-beans, Jak can keep Cow intact and help her people. But what the friends find in space is anything but safe.
