Of course, many fans have also created their own Rick and Morty themed pumpkins, including these Mr. Meeseeks pumpkins, which definitely aren't terrifying...

And speaking of Mr. Meeseeks, fans should be excited to learn that Rick and Morty co-creator Dan Harmon might be including the species in season 3.

"I'm going to make that a personal promise to myself. (Laughs.) I'm going to force Mr. Meeseeks into season three," Harmon told The Hollywood Reporter earlier in the month.

There is no premiere date set for season 3 of Rick and Morty.
