SpongeBob Day 10

Trigger warning death+suicide

SpongeBob Day 10

Creepypasta Au

Different from the horror au

I call it HashSlinging Slasher

In this au plankton brainwashes SpongeBob to be the hashslinging slasher and kill all his friends

The first victim is Mr. Krabs who is after hours at the Krusty Krab counting his money and is attacked and knocked into a grease trap

The murder of Mr. Krabs is all over the news and Sandy suspects it was no accident so she enlists spongebob to help investigate

When his brainwashing kicks back in the next night he targets Squidward but isn't able to get him but raises suspicion with Patrick

Before SpongeBob can go after Patrick Gary attacks him because he notices SpongeBob is not himself but SpongeBob bashes the poor snail to death

The next night SpongeBob gets Squidward alone, cuts off two of his legs, and chokes him with his clarinet but just then Sandy and Patrick arrive but SpongeBob flees

Sandy then confronts SpongeBob and tries to save him she succeeds but not before he's already slaughtered Pearl, Larry, Bubble Bass, Fred, and Mrs. Puff

After he regains his senses he doesn't stop trying to grab Sandy but she pushes him away confused not realizing he was trying to save her from a bomb that was planted in her suit during the scuffle

Now SpongeBob confronts Plankton and Karen

Karen informs SpongeBob that she knew this was going to far and had to be stopped and that Plankton captured and began torturing Patrick to make him the new killing spider and to make it irreversible. She tries to help him but it's too late for that and SpongeBob smashes her screen.

He then confronts Plankton who begins explaining his plan but while he's distracted SpongeBob snags a bottle of acid and burns plankton with some acid bubbles but not before Patrick is released and sent after SpongeBob

In the battle of the friends SpongeBob is force to kill Patrick

Afterwards he picks up Patrick's gun and finishes himself off

Spongebob Anniversary Day 8???

Redesign universe

This is my take on the characters designs making them slightly more accurate to the creatures they're based on and giving them some more shape personality

Shout-out to my friend who helped with these and practically designed Squidward for me or was at least a big inspiration

Spongebob Anniversary Day 7

The Spomgevengers

Based on an old au I made I don't even remember all the fusions

All I remember is Hulk and Patrick, Gary and Nick Fury, and Plankton and Thanos. The rest I just thought fit. Squidward and Hawkeye cause both don't offer much to the Table. Krabs and Captain America cause both are war vets. Sandy and Iron Man cause both are smart and wear special suits. And SpongeBob and Thor cause I thought his spatula would be a good replacement for the hammerI even did this on my Marvel book as a surface to write on

SpongeBob Anniversary Day 6

SpongeBob Anniversary Day 6
SpongeBob Anniversary Day 6

This is a dark somewhat Underfell style au

SpongeBob is a jittery ball of anxiety whos always getting into trouble and is constantly roped into Patrick's schemes

Patrick is still an idiot but an idiot with goals. He's always trying these get rich quick sort of schemes that usually gets him and SpongeBob into trouble. Also as a running gag he constantly accidentally injures himself gruesomely

Plankton actually tries to help Bikini Bottom and wants the Krabby Patty formula to try and give people more affordable food. Unfortunately he's always squished but he never gives up on his dreams

Squidward I'm still working on but he has basically completely lost it. His art is often very dark and twisted usually featuring lots of gore or suicidal themes however he is a significantly better artist than in OG SpongeBob universe. He's currently taking anger management and frequently has heart attacks

Sandy is a mad scientist who came to Bikini Bottom to run inhumane experiments on the sea life. She likes toying with SpongeBob and Patrick tho they are probably the people she treats the best. She teaches SpongeBob self defense but not karate rather she teaches him dirty tactics on how to win street fights

Mr. Krabs is a war veteran and is a very stuck in the past kinda guy. Not open to any new ideas which has made his business very unsuccessful. So he resorts to underhanded tactics to eliminate competition to make his restaurant the only place for common folk to get food but it's still very expensive. He's a strict boss and has no problem killing anyone who tries to steal his money, formula, or points out his little arm

I also did some human designs for this au

Spongebob Anniversary Day 4

Spongebob Anniversary Day 4

Horror Au

After human scientists stole Neptune's Moon, the magical rock that controls the evolution of the SpongeBob cast, the creatures of Bikini Bottom were stuck mid evolution between primal and evolved. Besides being unsettling these creatures have large appetites and after they lost the ability to read they soon were unable to use the Krabby Patty Secret Formula and food became scarce. They then resorted to eating each other. Manray, who was one of the few to keep most of his intelligence, set his sights on larger prey and began preparing a super weapon to kill humans on a large scale for his feast. So it's up to Sandy to stop him while surviving in this hellish distorted version of Bikini Bottom

Spongebob Anniversary Day 3

Spongebob Anniversary Day 3

My take on Spongetale

SpongeBob is Papyrus, Patrick is Sans, Plankton is Chara, Sandy is Undyne, Squidward is Alphys, Mr. Krabs is Mettaton, Bubble Buddy is Flowey but with elements of the Dirty Bubble

Instead of different soul colors they will instead affect your soul in different ways like Undertale Yellow. Patrick and SpongeBob will trap you soul in a bubble making the game into a flappy bird style Sandy will lasso your soul which would be the same as when Starlo lassos your soul in Undertale Yellow, restricting your movement to a spinning circle area. Squidward would give your soul a string with money when fighting Mr. Krabs on it which will swing with your soul and if it's hit by a yellow attack (which will have a circle on them) it will grab it and you need to pull in the opposite direction to escape. So basically in the fight you need to protect that coin from being grabbed

Songs: Bubble Buddy:

Your Fun Friend (You Best Friend)Your Fun Nightmare (Your Best Nightmare)

SpongeBob: Blah lah lah (or however you'd write out his laugh sounds) (Nyeh heh heh) Bubblebussle (Bonetrussle)

Patrick:pat. (sans.) Uh...This Is My Song I Wrote For Myself (STMPWYFS) PLANKTOSTAR (MEGALOVANIA)

Sandy:HI-YAAAAAH! (NYAAAH!) Lasso Of Texas (Spear Of Justice) Brawl Against A Texan Hero (Battle Against A True Hero)

Squidward: Squidward Tortellini (Alphys) Belongs In The Trash (Here We Are) Squidward Finishes The Errands (Alphys Takes Action)

Mr. Krabs:Krusty Krusher (Metal Crusher) Death By Krabbrog (Death By Glamour) Power Of BIG MEATY CLAWS (Power of NEO)

Plankton:Microorganisms (Stars)PLANKTO RETURNS! (MEGALO STRIKE BACK)

She Now Also Has A Sprite

She now also has a sprite

The battle sprite isn't finished yet

Underfell Toriel

Underfell Toriel

Toriel: Prisoner of the Ruins Once a powerful queen her husband started taking his frustrations out on her with verbal and sometimes physical abuse. She learned to stay mostly quiet until her beloved child Chara was killed by her husband She lashes out and got a good portion of her face burnt She was banished to the Ruins where she slowly went insane. She became detached from reality Refusing to believe anything has changed. She made herself her own fake family out of training dummies from the Ruins They don't talk so she talks for them. Any human she falls she thinks is Chara.....and when they leave she relives that moment when she lost her family and shuts herself away for a week, not eating or sleeping before returning back to her delusional self again. She is dangerously over protective, killing any monster who talks to you when she's around. She has severe abandonment issues. Staying with you most of the Ruins When you try to leave she decides to destroy the Ruins exit once and for all but after being forced to fight you she plans to destroy the entire Ruins Because if she can't have you....no one can. Asgore can't get your soul if she does right?Ultimately she lets you go. Before going back to her stuffed family.... baking pies with the dust of monsters....

Underfell Frisk, Flowey, Asriel, and Chara

Underfell Frisk, Flowey, Asriel, And Chara

The trauma children!

Trigger warning for suicide and abuse

Frisk is the human you play as. Quite simple. They bonked their head on a stick on the fall down luckily they're good with first aid. They're a friendly child despite all the shit they went through. Their birth parents were abusive and the trauma rendered them mute with minor PTSD. They were put in an orphanage but escaped and went to commit suicide by diving into Mount Ebott but by a miracle they survived and saw it as a sign from God that they have a mission and after meeting Flowey who presented himself as a fallen angel they set on a quest to heal the wounds of an underground torn apart by the death of a child and the failure of a king.

Long ago monsterkind was ruled by Asgore and Toriel and their son Asriel and later their adopted child Chara Chara was the adopted child of the Dreemurs their past is something they are holding me at knife point not to discuss so don't ask. They are Asriel's only real friend. Things were rough even with the Dreemurs Toriel and Asgore were always bickering and it usually ended with Toriel sleeping outside the castle. Asgore wasn't cold hearted but incredibly stressed because the underground was in great peril and everyone was turning for him for help. He still cared about his family but put his kingdom first. He loved Asriel dearly and tried to make Asriel a better king than he ever was but he never did care much for Chara He believed Chara was a bad omen. He didn't trust humans after they betrayed his kind so long ago and neither did the rest of monsterkind One day monsters stormed the capital demanding Asgore kill and harvest Chara's soulIn a moment of weakness....he killed his own child. Toriel lashed out at him and he in a fit of rage and confusion snapped off her horn and banished her. Asriel horrified by this took Chara's soul and ran away to the surface but was not welcomed by humans who killed him brutally That was day Asgore lost everything And it was all his fault. That was the moment that broke Asgore and would lead to the downfall of his kingdom. A while later the scientist Alphys, who began to slowly descend into madness after learning the truth of what happened to Gaster, Toriel, and Chara at the hands of Asgore, extracted determination from the souls of dead humans to imbue life onto a flower. Not just any flower. But the first flower to grow from pollen brought from the surface from Asriel And so Asriel was reborn as Flowey He only has one goal: escape. However he doesn't remember anything about how he died Just that he was once a prince. He accompanies you in every route of the game acting as a guide, mentor, and bodyguard In the genocide route he adopts the motto "Kill or be killed" and through the players bad influence becomes like the Flowey from Undertale In the neutral route he betrays you. Not Frisk He actually cares for Frisk But YOU the player. He knows that once you escape you'll just reset again. Take away your happy ending Take away his happy ending Take away everyone's happy ending So he turns into Omega Flowey (who resembles a biblically accurate Angel) to fight the player specifically and try and save everyone In a way he's the true hero of the game. In the pacifist route it's mostly the same except after seeing your friends he has hope that you won't reset, that you'll give everyone the happy ending he's been hoping for and he absorbs the souls and all of monsters to destroy the barrier and save everyone....until he becomes Asriel....He suddenly remembers the events of his death and realizes the underground isn't worth saving....No one isSo he sets out to put this world out of its misery. But through the power of friendship you convince him that there is still hope and that your dreams are able to come true and he destroys the barrier.....And everyone lived happily ever after......until you betray them all..... because well.....there's other endings to get....you just have to see every possibility......you're never content even with everyone happy.....and so you reset again. Just to see what would happen if you.....i don't know...Killed everyone? =)

Underfell take

Underfell Take
Underfell Take

My take on Underfell Papyrus. He's this over the top supervillain and co-captain of the Royal Guard. He's a bit of a kiss ass to the king and takes his job very seriously.

He has two separate outfits here one that he wears when harassing you through Snowdin that covers his mouth because he is embarrassed by his crooked messed up teeth

And his battle armor which is too heavy to move in properly so he only wears it during the final battle since he's just using bone magic on you

Side note I have no idea what I'm doing in math now

this makes me cry but in a good way

Concept: A gender reveal party but AFTER the kid is born.

Like when the kid is 6 or 12 or 18 or 24. When the kid has decided what their gender is or isn’t.
