In the beginning of the short, Flipper and Jagger talk about the upcoming holiday, Halloween, and Flipper finds out that humans carve pumpkins instead of pineapples for the holiday.
The next day, Felicia tells Flipper about the Ghost of Nickelodeon, who has been seen roaming the halls of the Nickelodeon headquarters, after the latter tells her that he has never been scared. Flipper, disbelieving the existence of the ghost, is going to his work desk over the headquarters one night to pick up some Nickelodeon slime for Jagger, when he encounters the ghost: he starts panicking, and tries to escape from the room. Suddenly, Jagger comes in there to uncover the one who's responsible for scaring him. It turns out that Felicia and Jagger were trying to do so, as the short ends.
