Hopper and Wilson fetch a star / Maria van Lieshout.

Enhanced descriptions from Syndetics:

Have you ever wanted your very own star?

Wouldn't it be wonderful to have your own star for a nightlight? It is this thought that begins Hopper and Wilson's second adventure. They fill their airplane with lemonade and soar into the night sky. So many stars to choose from! One is too pointy. One is too heavy. Another is too bright! Taking a break on the moon, the two friends look directly above and spot it--the perfect star! As Hopper lays down for a nap, Wilson ventures off on his own, to the dark side of the moon. Yet now he is lost! How can he find his way back to Hopper?

The perfect star, of course. Wilson spots it in the sky and follows it back to his friend. In another deceptively simple story, Maria van Lieshout shows how sometimes the best part of nature is that it's found only in nature--and that everything has its proper place . . . be it stars or even best friends, who always belong together.
