Goomby

Goomby turns up as one of the many odd, quickly-sketched figures who drift through the chaos of Rick and Morty's universe, voiced with the loose, improvisational energy Justin Roiland brings to the show's stranger corners. He exists on the margins of a bigger story, present mostly to add another jolt of the show's anything-goes weirdness.

What makes a character like this work is less backstory than texture — Roiland's vocal performance, half-mumbled and offhand, gives even a minor figure a distinct comic rhythm. The show trusts its universe to be dense enough that a passing oddity can land a joke and vanish, and that trust is part of its charm.
