"Pickles" is a bit dumb, but still good episode for the series. It's unclear who this Bubble Bass is and why everyone care about what he thinks about food. It's also unclear why Bob couldn't just show him pickles in the burger before giving it to him. But who cares? The episode is really funny and SpongeBob is just SpongeBob like always. Everything got mixed up in his head... I love how even the music was reversed, when Krabs came to Bob's house. And I can't not laugh at Squidward every time watching this episode... That's how you make a hilarious supporting characters. Bubble Bass casually throwing him everytime is gold.
Also "Marmaidman and Barnacleboy" episode introduces some real retired Bikini Bottom superheroes and I'm personally not a fan of M&B episodes (especially the titles of their episodes, so unique...). Their first appearance is just okay and there will be better M&B episodes, but it's definitely not the worst one. However, it's "Pickles" what carries the episode.
