10/2 through 12/19
Nebular is one half of a pair of aliens, the other half being Galaxoid, that landed in Calvin's backyard. At the time, he was collecting leaves for a homework assignment at the last minute.
Galaxoid and Nebular claimed that at light speed, their ship could "just make it" to a short stop on their planet and back to Earth within an afternoon. Although their estimate proved somewhat liberal, the fact remains that their planet must have been only a few light-hours away.
- According to Susie, the leaves from the aliens' planet looked like weirdly cut maple leaves.
- Galaxoid was not referred to by name until Calvin exclaimed in shock at their second appearance, although Nebular referred to himself by name in the duo's first appearance.
- Galaxoid and Nebular claim the reason they want the Earth is "prime real estate".
- Similar to Moe, the duo speak in an unusual font— squarish, computer-like letters.
