The Magical Pony #3: A Country Vacation

Vigga is on vacation at her aunt and uncle’s farm.
She brings Luna, but keeps her hidden in a bag, because she doesn’t want the adults to see her.
One day, Vigga and Luna go for a ride in the area and find a little cat that looks badly neglected.
Who would treat an animal this way? It’s up to Vigga to find out and do something.
