If you could wish upon a star and know it would come true, what would you wish for, and what would you do?

One bright star shines over the night sky, and children everywhere have a wish ready. One would ride a giant dog to school. One would be a princess in a castle in the clouds. One would grow a fish tail and sing with a whale. Others would control the weather so the family farm can grow, open a sanctuary where every lost animal feels loved, teleport across the world to hug faraway family, or use the power to heal so Grandma feels well enough to go out for a meal.
