Spongebob noticed the type of classic sounding music from the 1950's playing in the background while grilling Krabby Patties at the Krusty Krab, making him think as he rubbed his chin.
"You know this music sounds good and all, but I would kinda like to see just why it's playing at all." Spongebob asked himself as he ate a finished fresh burger, taking the time to savor in the Krabby Patty as suddenly a portal appeared next to him, sucking him up as he screamed.
"Spongebob! Quit bellyaching on the job and-" Mr. Krabs snapped as he opened the door, only to see that his fry cook wasn't there. "Aye? Where did he go?"
"Wherever it was, I'm happy for it taking him away." Squidward said as he rubbed his big nose while reading through a magazine.
Spongebob groaned as he looked around to see that he was in a suburban area, noticing a blue hound casually strolling down while dressed like a mailman. "Hey, excuse me, Mr. dog!"
"Oh, why you can just call me Huckleberry Hound. Although my friends call me Huck," Said the cartoon dog as he wasn't fazed by the fact that a yellow sponge was speaking to him. "Are you lost?"
"Well, kinda. I'm Spongebob Squarepants, and I'm from underwater!" Spongebob explained while doing various poses that could only be executed in a drawing. "I don't know how I even got here!"
"Oh, sounds like you're in a fanfiction." Huck chuckled as he patted the concerned sponge. "Don't fear, just several more chapters and you'll be back home, I can assure you."
