Dolphin Dilemma

Zom has told Jack and Skel about the dolphin city for weeks - towers of coral, streets of shells, and dolphins that flip through seaweed hoops. But when the three friends finally dive beneath the waves, something is terribly wrong. Why are the dolphins so exhausted? What are those spiny green creatures smashing the reef to pieces? And can three small heroes really stand up to monsters twice their size? This decodable reader practises the ough phonogram in words like ’thought,’ ’tough,’ ‘rough,’ and ’thoroughly.’
