There were a lot of things Cat didn't know when she moved to outer space. She didn't know the food was all made from squished beans. She didn't know there were mean kids named Weed. And she didn't know you had to keep your room clean all the time. But her new friend Arkali is pretty cool, even if he's never eaten a real apple or met a unicorn. Now they have a sick plant in the ship's biosphere, and even magic and rabbit-poop tea aren't helping. Can Cat and Arkali find a solution? Eleven full-page interior illustrations make this a fun read! Reading level is similar to Magic Tree House books.
