It's Ricky Ricotta's birthday, and as a special treat, his parents are taking him and his Mighty Robot to see dinosaurs at the museum. Too bad they've also invited Ricky's little cousin Lucy--she's a real pest! When they get to the museum, all the dinosaurs are missing their heads . . . because an evil spacebunny from Jupiter has used the dino DNA to create Jurassic Jack Rabbits! Now it's up to the entire Ricotta family, including Lucy, to stop them from taking over the planet. With their easy-to-read language and action-packed pictures, the Ricky Ricotta books are ideal for beginning readers.
