Morty Crumplestein
In “Meeseeks and Destroy,” a notable Season 1 episode, Rick provides a solution to his family’s ever-pervasive issues in the form of Mr. Meeseeks, a creature that was created to solve problems. He can’t fulfil his goal and disappear for good until these problems are solved. However, in true Rick and Morty fashion, this takes an unexpected turn.
When Mr. Jellybean arrives on the scene, you can see that he’s a nod to Crumply Crumplestein, a character that’s the brainchild of Rick and Morty co-creator and star Justin Roiland. If you take a peek at the above images, you’ll note that the design is almost identical. Mr. Jellybean just looks less … crumply.
