Space explorers Rover and Speck are on a dangerous new mission: visiting Unexplored Planet K2-18b. It doesn\'t take them long to encounter a frightening inhabitant-a blubber beast-or to find themselves inside its mouth! Luckily, they manage to escape unharmed. But when they learn that a local creature has been swallowed by the Beast, they know they alone can rescue him. They\'ll have to go back in! Can they succeed? Or will they-gulp-get swallowed, too? The fun is out of this world (even though they\'re inside the belly of the Beast!) in this hilarious second book in the Rover and Speck series!
