Original Raw and Uncut
Two-Headed Starfish
Early season four episodes have a pre-movie-ish vibe to them. Especially episodes like "Lost Matress", "Have You seen this Snail", "Shell of a Man", "Skill Crane", etc. Some of these very early season 4 episodes could easliy pass as season 3 (When I was younger, I used to think that the lost matress was a pre-movie episode, but the only giveaway was that spongebob didn't have his deeper pre-movie voice). Even there was mild adult humor thrown here and there throughout season four. Plus, the art style and music of S4 seems very outdated when compared to episodes from now (especially in the first half of S4). The second half of season 4, can easily pass for season five. "Pink Purlioner", "The Best Day Ever", "Squid Wood", "Driven to tears", "The Thing", etc. Mainly because by the end of season 4, the post-movie swing of things is already adapted. Especially when it comes to animation, humor, and story-telling styles. Matter a fact, I even read somewhere that the first few episodes of the season finished production shortly before the 2004 movie hit theaters.
