Follow a group of three-inch tall family fairies — or as they’re known in the fairy world Dew Drops — who live inside teensy fairy houses on brownstone balcony gardens in “The Big City.” They have been assigned to human families to secretly help out around the house with the little things that can often fall through the cracks, like making sure your first lost tooth actually makes it under your pillow before bedtime or your favorite toy doesn’t get left behind at the park.
