When summer arrives on Nebulon, Zack discovers that his best friend, Drake, is afraid to learn to swim and decides to teach him before they go on a trip to water-covered planet Araxie.

Zack and Drake venture to Gluco, the candy planet, for some Easter fun but while competing in such activities as an egg toss and a three-legged race, Zack is so determined to come in first that he considers cheating to win.

When a cosmic storm hits, stranding the Nelsons on their new home planet, Nebulon, Zack's hopes of a white Christmas in Vermont are dashed, but Nebulon provides a surprising alternative.
