"What's black and white, and flies faster than the speed of light? The Space Penguins! They're the ice-cool crew of the spaceship Tunafish. With their pioneering flying skills and resistance to the deep freeze, these intergalactic avians are going where no fin has gone before. Captain T Krill, Rocky Waddle, Fuzz Allgrin and Splash Gordon are on a mission to explore new planets, rescue alien life, and battle their former comrade-in-wings: DarkWader. In book five of the Space Penguins series, the penguins accept an invite to take a holiday on a new leisure planet. But little do they realize they're waddling into a trap. Before long they find themselves the number one attraction in the planet's zoo. Can they rescue the zoo's other aliens and break out, or is it a life behind bars for the penguins?
