Plot
Ickis and Krumm are trading monster cards with two other monsters when Oblina comes around and asks to join, only to be rejected due to the fact that trading cards is a "guy thing." They leave the dorm, leaving an infuriated Oblina behind. When Ickis and Krumm return to their dorm, they find that Oblina is having a slumber party with Harriet and Dizzle. Oblina rejects Ickis and Krumm, saying that she is doing "girl things" with Harriet and Dizzle, much to the guys' dismay.
Meanwhile, at a human's house, a trio of female humans are having a slumber party of their own, and the female monsters decide to go out for a scare. They come across the house where the female humans are having their slumber party in and proceed in scaring away the female humans.
Meanwhile, Ickis, Krumm, and the other two male monsters are bored and decide to bug the girls during their scares. The girls attempt to scare the cheerleaders at the gymnasium of a local high school during the impending varsity volleyball game, but are squelched when Krumm has already accomplished the task and proceeded in scaring away everyone out of the gym. The girls demand the guys to leave them alone during their scares and walk away.
At a local bookstore of the Valley View Mall, Ickis steals the girls' thunder once again when he scares away the humans out of the store. The male monsters end up scaring away every human in the Krazee Kone ice cream shop, stealing the girls' task yet again. So Oblina contrives a solution to make sure the guys don't interfere with the girls' scares again.
So they sneak into the Wax Museum and the male monsters spy on them doing so. They sneak inside the museum and discover that the girls are nowhere to be seen. So they decide to look around for them and find a number of humans inside one of the rooms. The guys enter a workshop staff room, which capriciously becomes dim. They view robotic versions of Santa Clause, Little Red Riding Hood, and Abraham Lincoln. Thinking that they are humans, Ickis attempts to scare them. But the robots make no reaction and continue moving. So Krumm and the other two monsters try to finish the job, but to no avail. Knowing that their tactics are futile, the guys run out of the building and discover that Oblina, Dizzle, and Harriet have been fooling them the whole time. As the guys leave while the girls taunt them, Ickis tries to climb through the window, but ends up setting off the alarm. A human security guard grabs Oblina and ends up getting scared away by Ickis as the monsters make their way out of the building. Oblina, Ickis, and Krumm reunite and start kicking each other as they begin laughing together.
