Zack is thrilled when he finds out that his best friend on Earth, Bert Jones, is going to visit him on Nebulon. Zack can't wait to show Bert around the new planet, as well as his new school. But when Bert meets Drake, Zack's best friend on Nebulon, some jealousy starts to brew. Drake feels left out when Zack and Bert tell stories from Earth and share inside jokes. And he feels even more left out when the three boys go to an amusement park on the planet Cisnos and Zack and Bert go on all the rides...without Drake. When Zack finally realizes how out-of-place Drake feels, he, Drake, and Bert decide to all have fun together. Because, of course, two best friends are even better than one
