It was a sunny day in Bikini Bottom. Spongebob was at the Krusty Krab serving the customers as usual. Squidward was behind the register and was reading, "Fish Life." magazine. Spongebob then walked to his quarters and saw a bottle on the counter. Spongebob stared at the bottle for a little bit and opened the lid. Patrick suddenly barged into the Krusty Krab and went to where Spongebob was.
"Don't open it Spongebob!" Patrick yelled.
Spongebob paused and asked Patrick confused, "Why? What is this stuff?"
Patrick snatched the bottle out of Spongebob's hand and said, "It's this potion I got from the carnival this morning! He said that if you drink this potion, you'd turn into a werewolf!"
Spongebob turned around and glanced at his calendar and saw a huge circle around the 31st, which was Halloween. Spongebob then faced Patrick and said, "Okay Patrick. I'll watch this potion for you!"
Patrick looked at the bottle and placed it on the counter and said, "Okay. I'm going to run a few errands and be back to return the potion."
Spongebob winked at Patrick as he left the room. As Spongebob was working, all he could think about was the potion in the bottle. After his shift, he walked home with the potion and said, "Working sure is thirsty business." and opened the bottle and drank the potion all in one gulp. Suddenly, Spongebob's ears turned big like a werewolf and Spongebob gasped. "What have I done?" he thought and quickly ran home.
Once Spongebob got home he dashed through the door and locked the door and closed the windows. Suddenly, Spongebob's teeth became sharp and Spongebob gasped and quickly called Sandy.
"I need help! I drank some of Patrick's potion he got and now I'm turning into a werewolf!" Spongebob said into the phone.
"Sure thing Spongebob. Come on over to the Treedome and I'll make a new potion for you so you'll be back to normal!" Sandy said and hung up.
Hours later, Spongebob was sitting at home watching television. Surprisingly, Spongebob was covered with brown fur. Then his pants ripped and Spongebob began to growl! Spongebob then walked over to the Treedome slowly and grumpy. Once he reached the Treedome, he jumped onto the roof and snarled.
"JIMMY!" a fish yelled. "DON'T GO NEAR THAT MONSTER!"
The tiny fish turned around and said, "But mom, it's Chewbacca!"
Spongebob then turned around and slashed the little fish to tiny pieces and the other fish ran away sobbing.
Sandy looked up and saw Spongebob and quickly ran outside.
"What are you doing?" Sandy asked.
Spongebob ignored Sandy and started snorting loudly. Sandy gasped and then quickly made a potion and gave it to Spongebob. Quickly, Spongebob threw the potion onto the ground and ran to the Krusty Krab, stomping madly!
"Is there a problem?" an officer asked.
Sandy turned around and said, "No sir."
The officer gave Sandy a serious look and Sandy sighed. Then the officer walked away.
It was almost dark out and Patrick was at the Krusty Krab until he saw Spongebob slashing through the Krusty Krab. "SPONGEBOB NO!" Patrick hollered and jumped onto Spongebob. Spongebob sneered and slobbered everywhere. Patrick pulled out a tiny screwdriver and jabbed it in Spongebob's head and then suddenly Spongebob turned back to normal.
