Writers: "Gah! Writing an eleven minute episode is so hard. I know, maybe have complex enough plots to fill in seven minutes or even four minutes!" *cue Rise and Shine and Waiting.
Actually, I do think that this episode might have been what inspired season 5 to have some shorts, because it honestly feels like one. Although, this episode could have been salvaged. You know in the beginning where Spongebob thought he saw monsters in the dark? If they kept on that note and maybe have like a Rock Bottom in Spongebob's house this could have worked. Hell, he could have even purposefully called in Mermaidman and Barnacle Boy to help fight these monsters in his head. Oh, and Patrick running off into the sun was actually a good joke. Hell, I could even tolerate some of the screaming. But, when you have a four-minute plot stretched out to eleven minutes, it just doesn't work.
