After a small horse has been sent to the Animal Ark Veterinary Hospital, Mandy finds out it is a delivery for Tania Benster, the new girl in town whose parents have just divorced, leaving Mandy to show her how to care for the animal.
When Mandy and James find a runaway gerbil by the river, they are very surprised. The gerbil has been living in the wild and is not used to being around people.
The combined efforts of Andi and her friends fuel the search for an injured Labrador's owner, and their compassion for all animals inspires the Pet Finders Club to keep every pet in Orchard Park safe.
