Hmm, I’d give you a more in-depth answer, but that would require a month or so time for me to rewatch the entire series lol. I do have some vague memories of other more applicable episodes, but these that I’ve listed here will have to do because I don’t want to keep you waiting.
After a little research, here’s at least five eps I can think of, and my reasons for listing them:
Pizza Delivery (S01E10): Squidward and Spongebob’s interactions in this episode are hilarious, for one, but the part that really sells the Squidbob shipping here is at the end where Squidward tries to comfort Spongebob and then avenges him by slamming the pizza in the guy’s face. I know Squidward is an asshole, and he’d probably slam a pizza in a guy’s face just for looking at him funny, but I think it’s pretty sweet that he’d do it specifically for Spongebob, because somebody hurt him.
Love That Squid (S07E25): I like this episode because, again, the Squidward/Spongebob interactions are golden. In the beginning, Spongebob gushes about Squidward, and even says (and I quote):
“–You know what is the most amazing thing about Squidward? … uh… it’s his selflessness! His undying commitment to being a true friend! And I know anyone who is lucky enough to go on a romantical date with this guy would get to experience things on a whole ‘nother very special level!”
Seems he’s got high opinions on Squiddy all ‘round. ;) Plus, hey, “Practice Date” amirite? You just gotta fake it til you make it.
Dying For Pie (S02E09): Squidward thinks he fed Spongebob a bomb by accident, and feels really guilty about it, despite “hating” Spongebob. And so, he goes above and beyond for him, suffering through all of Spongebob’s ridiculous little activities, just to make sure his supposed “last day” is his best.
Squid on Strike (S02E26): We all know Spongebob loves his job, but he chooses instead to side with Squidward when he goes on strike against Krabs. And Spongebob adheres diligently to Squidward’s teachings, despite the fact that they go against the Krusty Krab, and does his very best to please him and make him proud.
Squilliam Returns (S03E12): Another instance in which Spongebob goes above and beyond what is expected of him, just to help Squidward.
BONUS: The Two Faces of Squidward (S05E33): This episode receives an honorable mention simply because Spongebob tells Squidward he loves him no matter how he looks and Squidward says something along the lines of how he almost wishes that meant something. ;)
I hope my answer wasn’t too long, and it was to your satisfaction. ;w; I’d do better if I had a bit more time to rewatch the episodes lol.
