Stay tuned for another exciting episode of Black Hole Radio-Nebulis! Hawk, Matt and Celeste and all the sixth grade are going on a field trip to . . . the Planetarium! It's going to be so cool because Matt has permission to make a rap music video in the interactive space room. What could go wrong? Plenty when Hawk accidentally pushes the ON button on the black hole radio in his backpack! Big Yikes! The friends are swept away to Planet Nebulis during a deadly dust storm. Luckily, they discover an oasis. It's a beautiful bioluminescent jungle, with enormous trees, flowers-and plant people. They find out that the planet's life crystal needs to be reset to restore balance to the planet and their Protective Dome. Can the friends help them to access the crystal buried at the core of the planet? And will the nasty space pirates find a way in before they can fix it? Stay tuned!
