Blah-blah Dimension is a dimension in which every inhabitant only says the word "Blah" instead of normal language.
Mooch Jerry, who visited Jerry 5126 and showed him rifts of the multiverse, led him to this dimension. During their visit, they see the local Rick and Morty were trying to push a giant ant they got on one of their adventures into the Space Cruiser. Jerry 5126 stated he somewhat understood, while Summer from this dimension came to Jerry (mistaking him for the Jerry of her world) crying about something. Not quite getting what she's saying, he only answered with a single "Blah" with a questioning tone, which seemed to have upset Summer even more and she ran off.
Trivia[]
- Despite the inhabitants of this dimension only ever saying the word "Blah", Rick's "Time Travel Stuff" box in the garage is labeled in normal English, unlike similar instances of dimensions from "Edge of Tomorty: Rick Die Rickpeat", in which all boxes are labeled to accompany the theme of their dimension.
