From Other Dimensions
- Unknown Dimension (possibly the space-time continuum or even the Void
This dimension features multi-colored squares, in different places which disappear when lifted, and it comes with a blank white background. Mysterious voices lurk around and copy words that are said (while spelling them out using goofy fonts), and it's hard to get out as running around here will take you back to where you started, as inspired by The Matrix. However, the time machine is always right under where you stand (revealed in SB-129). The only known way to access this place is to destroy the time-switch activator in a time machine. Squidward is the only known character to have gone to this dimension.
Parallel Bikini Bottom
An opposite version of Bikini Bottom; the only known inhabitants are parallel versions of SpongeBob and Patrick. Parallel SpongeBob has been seen in several episodes, including "Wet Painters" and "Something Smells," while Parallel Patrick has only been seen in "Rule of Dumb" and "Roller Cowards."
the 9th Dimension
A dimension mentioned in "Big Pink Loser" and in a video game. Not much is known about this dimension, except that there are giant monkey men out to destroy it. Patrick's lifelong goal is to find a way to access this dimension, defeat the giant monkey men, and save its inhabitants. It probably doesn't exist, though.
the 8th Dimension
A dimension also mentioned in "Big Pink Loser." Like the 9th dimension, not much is known about this dimension, except that there are creatures trying to destroy it. The creatures are known as the little monkey men, which are similar to the giant monkey men in the 9th dimension, but much smaller. Patrick mentioned this when SpongeBob told him that trying to defeat the giant monkey men and saving the 9th dimension would be a little hard in "Big Pink Loser." Like the 9th dimension, the 8th dimension probably doesn't exist, either.
