I do not own anything in this story
I dislike made up stories about characters (by which I mean fanfics) because in my opinion they make fun of the characters
however after seeing if others shared my ideas about characters I realized like TV and video games they may be windows too other dimensions
(ever put your finger hard enough on a computer it gives kind of a portal effect) (like the entrance to Hazy Maze Cave in Super Mario 64 and DS remake)
fanfics may be parallel dimensions to those said dimensions so please if you write a fanfic don't do anything too drastic. If you cant find any of my stories then they have been deleted but don't worry it most likely means it's being updated.(because I have to use notepad)

Spongebob had just finished defeating Link in a battle when...

Warning! Challenger approaching.

As Spongebob exits his pineapple house, he finds himself in a familiar place.
"Ooooo It's the Krusty Krab!" the sponge says admiring the stage as another pineapple arrives as Sandy exits.
"Sandy!?" Spongebob says taken back. "Yeahaw, Spongebob prepare to be defeated!" mocks the squirrel.
Spongebob is just about to grab a nearby hammer when Mr. Krabs crawls out of his office and steals it.
Distracted by Mr. Krabs the sponge gets hit by Sandy's lasso grab as the girl throws him away.
"So that's how it's going to go down... LooLooooLoooooLoooooo!" Spongebob says uttering a battle cry as the scene changes as they find themselfs in Jellyfish Fields.

Sandy launches a karate kick toward the sponge when a swarm of jellyfish get in the way forcing her to dodge.
"Got to stay away from those jellyfish, or that'll be a gnarly instant KO." Sandy advises.
This time Sandy tries to hit The Sponge with an uppercut, but the frycook reduces the damage with his shield.
Spongebob then catches an assist trophy out of the corner of his eye, the sponge leaps for the item carefully dodging angry jellyfish.
"Patrick!" the yellow sponge cries in shock as his friend comes out of the item. "Duhhhhhhhhhhhhh" the starfish says holding the orb of confusion stunning the squirell.
Using the Fry Cook, Spongebob is able to deal massive damage before his opponent recovers. Next the fighters find themselfs inside Squidward's house with said octopus pacing back and forth.

"Hey Squidward!" Spongebob replies cheerfully. Sandy karate kicks the sponge to the edge of the arena.
Sandy is about to deliver a final blow when she passes Squidward who starts yelling damaging her.
Both fighters damage is dangerously high, one hit could end the match. Suddenly Sandy grabs a Smash Ball and turns into the giant RoboSandy from Battle for Bikini Bottom!
Her attacks now stronger, the robot heads toward her foe when they end up back in Jellyfish Fields and the squirell gets KO'ed by jellyfish.
