The episode starts off with Squidward sleeping, but then he hears SpongeBob and Patrick's voices. He wakes up to see them in his bedroom. Squidward angrily questions why they are at Squidward's house to watch the sunrise with him. After Squidward finds out that they have snuck into his room every morning to celebrate holidays like Easter, Valentine's Day, and the Fourth of July, it is told that his brain has a thunder storm every time Squidward sees SpongeBob. His happy gland is forced to find shelter in his mind's recesses, but he gets the flu due to no recess deep enough, until the two leave.
Three hours later, Squidward installs an electric fence around his house to prevent SpongeBob and Patrick from intruding. He tricks them into picnicking on a catapult, which he uses to fling them outside the fence. To Squidward's surprise, the two land back inside and ask to be catapulted again, resulting in Squidward ordering them out. As he opens the activated fence's door, he is electrocuted, the electrocution clearing a storm over his brain. After SpongeBob unsuccessfully attempts to rouse Squidward and decides to go to the petting zoo with Patrick, Squidward awakens and asks if he could go with the two, to which the surprised duo agree to.
Squidward continues to express happiness and perform kind gestures for SpongeBob the next morning, such as waking SpongeBob up for work and flossing his teeth for him.
At the Krusty Krab, SpongeBob is surprised to see Squidward enter the kitchen, saying that he wanted to help SpongeBob work. SpongeBob promptly rejects this and Squidward is called out front by Mr. Krabs. He gives Susie a free hat, then asks for free refills. This shocks Mr. Krabs, who either calls cheap food or back into the kitchen he goes. Squidward returns to the kitchen, even making a fresh batch of Krabby Patties, but SpongeBob arrogantly rejects them, calling them "no good." He is stopped by Mr. Krabs when trying to throw them away, and is told they look fine to him despite SpongeBob's protest. SpongeBob becomes angry when he finds out Squidward has become a fry cook. Squidward expresses his desire to be Employee of the Month, with SpongeBob already being one a gazillion times, but the latter corrects him, saying a gazillion and six times.
Mr. Krabs then barges in to show SpongeBob a patty with a smiley face and dimples made out of ketchup. SpongeBob says that Squidward made it, expecting Mr. Krabs to be upset at Squidward. Mr. Krabs loves the design and makes Squidward Employee of the Month, much to SpongeBob's horror. Patrick even arrives with a cake for the award winner, which SpongeBob erases his name on the cake and replaces it with Squidward's.
Later, a party is thrown at Patrick's house due to Squidward being the new Employee of the Month. SpongeBob becomes enraged after seeing Squidward pogo-dancing with Patrick and yells at him, hurting Squidward emotionally and kicking him out of the party. Squidward attempts to enter his house again, but is electrocuted again upon touching the doorknob.
SpongeBob and Patrick come to Squidward to apologize for his behavior to Squidward, and SpongeBob slaps Squidward's hand, leading SpongeBob to getting electrocuted. Patrick joins too, saying "he wants to dance funny." The generator explodes and Squidward is returned to his normal, grumpy old self. But SpongeBob and Patrick's eye and voices change to look and sound like Squidward's, while Spongebob's nose changes to look like Squidward's and they pick up his behavior. They get into an argument with him, as the episode ends.

- This episode is available on the Bikini Bottom Adventures, Season 5 Volume 1, The Ultimate SpongeBob Box Set, The Underwater Stories, The SpongeBob SquarePants Collection, The SpongeBob SquarePants 8 Season DVD Collection, 2-Movies-Edition, The Best of Bikini Bottom, The Best 200 Episodes Ever, SpongeBob SquarePants Vol. 7, Loveable Sponge, From the Beginning, Pt.2, Complete Fifth Season, and First 100 Episodes DVDs.
- "Breath of Fresh Squidward" was ranked #30 during the SpongeBob's Top 100 event in the UK and Ireland from June 4-8, 2012.
- This episode was released on the Bikini Bottom Adventures DVD, released on June 5, 2007, over a month before it aired on television.
- In 2020 Nickelodeon released a hoodie that has the pictures of the photo booth from this episode as the left side of sleeve, and with images of "SpongeBob's Big Birthday Blowout" on the front and the back.
- Fourth of July is an American holiday, so Bikini Bottom celebrates American history.
- This is the first episode to use the track "Blue Tide."
- A scene involving Incidental 47 talking to Susie was cut. This part was retained on the animatic on Bikini Bottom Adventures DVD release.
- This episode reveals there is an employee bathroom in the Krusty Krab kitchen.
- The bathroom for boys is spelled "Buoys." This is a pun on the flotation devices.
- In "Employee of the Month," Squidward competes with SpongeBob to win the coveted title. However, it is unknown who won in that episode. This time, he earns it without even trying.
- When Squidward makes the Krabby Patty with dimples, he becomes employee of the month on the spot.
- Patrick's Employee of the Month cake is entirely fixed after SpongeBob replaces his own name on the cake with Squidward's. An icing drawing of SpongeBob is still on the cake even though he was not the winner of the award.
- SpongeBob shows some audacity in bossing Squidward around in someone else's home (Patrick's). In telling Squidward he was not allowed to pogo with Patrick, he was more or less telling Patrick what he could and could not do in his own home.
- The guests do not seem to be disgusted with SpongeBob's outburst at Squidward, as the party continues after Squidward leaves.
- In the Croatian dub, this episode's title is "Veseli Marko," which translates to "Happy Squidward."
- In the French dub, the 14th of July is mentioned instead of the 4th of July, as the 14th of July is the French National Day.
- SpongeBob's Employee of the Month Award photographs use his classic season 1 design, despite this being a season 5 episode.
- The scene where SpongeBob makes a smiley-face Krabby Patty and talks to it in a romantic way is a reference to its sister episode, "To Love a Patty."
- The title is a pun on the saying, "a breath of fresh air", which means that after several bad events, a good one finally happens, which fits the episode's plotline.
- In the scene where both SpongeBob and Squidward are making Krabby Patties on the grill, there are two grills in the kitchen instead of the one.
- In the same scene, SpongeBob has five fingers instead of four.
- Because there are 44 awards, it should be August or September, not February.
- When SpongeBob cries after Squidward becomes Employee of the Month, tears aren't coming out from his eyes.
- During the party scene, the bottom-most stripe on his party hat changes colors from red to white.
- When Squidward gets shocked, the gate's door is open, but when Squidward sadly goes home, the door is closed.
- There is a plothole; after the fence initially shocks Squidward, altering his personality, it blows a gasket and the security system breaks down. This would logically mean that Squidward could not possibly have been shocked back to normal at the end.
- At the ending, when SpongeBob and Patrick are electrocuted to become as cranky and grumpy as Squidward, their eyes and SpongeBob's nose adapt to Squidward's face, but when Squidward becomes the new Squidward, his face does not change the shape of them.
- When Squidward growls, his eyelids are miscolored.
- When Patrick changes SpongeBob's name to Squidward on the cake he does not change the drawing from SpongeBob to Squidward.
- In the Welsh dub, Luke Brookshier, Tom King, and Steven Banks are all listed as writers of this episode, even though none of them wrote this episode.
- Brookshier and King are also erroneously listed as storyboard directors.
- Xfinity/Comcast guides erroneously list this episode as "Breath of a Fresh Squidward".
