Ricky Ricotta's Mighty Robot Vs. the Uranium Unicorns from Uranus (Ricky Ricotta, No. 7)

Its Ricky Ricottas birthday and as a special treat his parents are taking him and his Mighty Robot to see dinosaurs at the museum. Too bad theyve also invited Rickys little cousin Lucy -- shes 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 its up to the entire Ricotta family including Lucy to stop them from taking over the planet.
