It's Halloween in Bikini Bottom. Just like every year, Spongebob becomes easily frightened by the holiday. So Spongebob decides to turn the tables and go as the legendary Flying Dutchman. Patrick helps him by making him wooden clogs and shaving him round, but no matter how much they try, Spongebob just isn't scary. Spongebob soon makes the saddest attempt yet when he hangs from a rope and scares the entire Krusty Krab Halloween Party. Everyone laughs at him and the real Flying Dutchman shows up uninvited. When he tells Spongebob that he just isn't scary, he takes off his ridiculous costume, showing the whole Krusty Krab show that he, Spongebob, actually go his whole skin shaved off while being shaved to round. He scares everyone out of the Krusty Krab and he finally becomes the scariest guy in town.
I was a Teenage Gary:
Spongebob and Patrick must go to the annual Jellyfish Convention in Ukulele Bottom for three days, leaving Gary all alone. So Spongebob gets Squidward to take care of Gary while he's gone. When the bus comes to pick up Spongebob and Patrick, Squidward finally becomes relieved that he's alone all weekend and tans the entire time, forgetting the snail. So three days later, Gary becomes desperately ill and Spongebob calls a vet. So Squidward must help Spongebob give Gary an injection from a shot. Then Squidward accidentally injects Spongebob, leaving Gary to grab a drink of water, which is all he really needed. So after the night, Spongebob starts to become more and more snailike until he turns into a snail and starts bugging Squidward. Then Squidward himself gets injected with the snail plasma and turns into a snail, leaving three snails meowing in the night.
