Rex has to hide a suspicious new dinosaur from creature-hating baddies in his fourth adventure. The final book in the laugh out loud series from a Lollies Prize winning author-illustrator, perfect for fans of Bunny vs Monkey and Dogman. Rex has a great gang of friends, from nine-year-old investigator Sandra, his best human pal; to Bigfoot, a jazz-loving yeti in disguise. But just occasionally, he does miss being around other dinosaurs. So when a new one appears on the scene, causing total chaos, Rex can't wait to welcome her and show her how to blend in. But there's something a bit ... strange about this new dinosaur. She can't understand anything Rex says. She doesn't listen to anyone. And she's very grumpy. Meanwhile, the evil Mr Beaumont (Sandra's ex-best friend Maddie's dad) and his BUMCRAC brigade of creature-haters want to rid the place of ALL dinosaurs. This time, they have a plan. Can Rex stop an all-out battle breaking out in the city he's made his home in? Highly illustrated throughout and laugh-out loud hilarious, this is perfect for fans of Dogman, Bunny vs Monkey and InvestiGators.
