It's actually two things, thanks to a friend of mine.
But I'm sure, he wrote a blog about SpongeBob's cosmology and had help from Última himself, thanks to this he is able to even have R>F in the real world of the series.
And it seems that there really is a way to interact with them.
He should comment here soon.
I'm still figuring this out, however, in the middle of it, I found a few things that explain why everything is so strange in the show, basically in the "real world" the writers change SpongeBob's stories to look for new
artistic visions of the same story, so Because of this, bizarre
stories emerged such as Mr Krabs being a
dictator, Squidward going to the future only to see that Krusty Krab still exists, etc., so much so that in an official
tweet one of the writers mentions that "Bikini bottom" is a nebulous place that is always changing, because of this certain inconsistencies happen
(Well, honestly, apart from SpongeBob's non-existent driver's license, there is a guide who says that Patrick is almost 2 meters tall and Nick says that Plankton is around centimeters tall, lol.), other things found were that the characters apparently work to make a story happen, this was shown in the
"Krusty Krab orientation video" and every time
the characters are aware that After "11 minutes" the episode will end and everyone will go home.
or also in those comic panels where SpongeBob instructs Patrick to start the story with the first panel, this in addition to Patchy
saying that SpongeBob is a star in the "real world" with him knowing that
Something that supports this further
is the friendversary itself, where SpongeBob remembers everything he and Squidward did together, which includes episodes in which supposedly it wasn't even them
And a funny thing, SpongeBob has access to "Popeye's" spinach (A parody of him)
