Rover and Speck have found a new kind of planet to explore-a gas giant! The pair don't know what to expect when they launch themselves from their spaceship, so they're thrilled when they find life there. That is, until shark-like creatures start shooting sparks at them! And things only get worse when Rover is zapped out of commission by one of their bolts, leaving Speck to save the day on his own! Thankfully, Speck makes a new friend, Jelli, who's happy to help him try to avoid the Spark Sharks and get Rover back to their spaceship for a reboot. But will they be able to do it in time?
