Mandy Hope loves animals more than anything else. She knows quite a bit about them too: both her parents are vets and Mandy helps out in their surgery, Animal Ark.
Mandy’s been spending a lot of time at the local dolphinarium, playing with two tame dolphins, Bob and Bing. The dolphins are happy performing together – but when Bob dies, Bing pines for company. Mandy and her friend Joel are worried about his future – until they come up with a daring plan to release Bing back into the wild – but will it work?
