Pablo and Splash by Sheena Dempsey

Antarctic penguins Pablo and Splash are polar opposites and besties for life. Pablo is a home-bird and a careful planner. Splash is easily bored and hungry for adventure. Sick to her flippers of the harsh, freezing weather, Splash persuades Pablo to go on a holiday with her. But far from the luxury beach destination that Splash has in mind, the pair end up in a time-travel machine that takes them back to the age of the dinosaurs. Suddenly their icy homeland doesn’t seem so dull!
