In the pilot episode, what seeds do Rick and Morty travel to collect?

In the pilot episode, Rick and Morty travel to collect Mega Tree seeds. Rick takes Morty to Dimension 35-C, whose conditions are ideal for growing Mega Trees, which produce Mega Fruit containing the valuable seeds.

Rick needs the seeds for his research because they temporarily enhance intelligence. After Morty smuggles them through intergalactic customs, the seeds help him recite advanced facts, including the square root of pi and the first law of thermodynamics, impressing his worried parents.

The seeds are sometimes confused with “Mega Fruit,” but the characters specifically travel to obtain the seeds inside the fruit. Their effects are temporary and unpleasant: Morty later writhes on the floor, while Rick admits they will need to return for more. The pilot aired on December 2, 2013, and establishes the show’s pattern of mixing absurd comedy with dangerous science-fiction adventures.
