Animal ark: mare in the meadow

Mandy and James are finding it difficult to spare enough time to give Camomile - a mare whose owner has gone to America - all the attention and exercise she needs. They are hopeful when they meet Angharad, who lives next to Camomile's field, that she will help them out. However, for her own reasons, Angharad doesn't want to get to know the mare. Can Mandy and James persuade their new friend to care for Camomile before she has to be sold?
