Norby's the bravest,
most outrageous, most lovable robot ever to save the day. Along with his
ever-faithful human companion Jeff, and a mischievious All-Purpose-Pet
named Oola, the three blast off for interstellar adventure.
First the trio search for a missing princess. But things get a little out of hand when, after they find the princess, she is accidentally turned into a tree. Norby, Jeff and Oola must get to the root of the problem quickly if they want to free the princess from her leafy dilemma.
Then a friendly, fire-breathing dragon is kidnapped from the planet Jayma. And once again Norby, Jeff and Oola must spring into action to rescue their scaly friend.
