Blythe opens the episode narrating her time having fun at F.U.N., or Fashion University North, with her roommate McKenna Nicole. Meanwhile, at The Littlest Pet Shop, the pets spend their days recounting the adventures they've had with Blythe while putting up with Madison, who now wears a haz-mat helmet and slides food to them from the doorway. They ready themselves at the webcam Mrs. Twombly set up for Blythe, but Penny regrets that they cannot see back at Blythe. While Blythe appreciates them jumping and cheering for her, McKenna brushes the behavior off and whisks Blythe away to class.
Over the summer, the pets have grown weary of having to fake their enthusiasm over the camera and soon notice Mrs. Twombly with a new shuttle van. They observe her polishing it for a few moments and eventually overhear Mrs. Twombly telling Madison it's for pickups and deliveries of pets and supplies and that she's set up a phone system for customer requests. This gives Russell the idea to send Mrs. Twombly a pickup request to Fashion University North so they can stow away in the shuttle and meet Blythe on campus.
Blythe has also grown weary at F.U.N., where she has a blast designing clothes but is incredibly bored with the technical and history lectures she's required to take. Eventually, she gets bored by her classmates too, who seem interested only in fashion and nothing else. When Blythe suggests they take a walk and pulls out a frisbee, McKenna and the other students at her table gasp in horror. McKenna defuses the situation by telling them Blythe is joking. As McKenna diverts the conversation topic back to her hats, she gets a text message and a photo from Jasper that he, Sue, and Youngmee are having fun at Zany Island, adding to Blythe's disappointment.
Blythe gets a moment to herself in Miss Westerkamp's class and uses it to call Madison over The Littlest Pet Shop, who is convinced Blythe needed a stand-in from an animal-related illness. Blythe fails to get any information about the pets or to talk to Mrs. Twombly before Madison abruptly hangs up. She does, however, discover that Fashion University North is preparing a shuttle to briefly stop by in Dowtown City for any homesick students from there and decides to get on board.
Russell sneaks onto Mrs. Twombly's computer and fills in a request for a pickup. Mrs. Twombly receives the pickup request from Russell and chooses to bring all of the Littlest Pet Shop regulars onto the shuttle. She proceeds to incessantly sing "99 Cans of Pet Food on the Wall," driving the pets crazy. In the other direction, Blythe falls asleep on the bus and has a nightmare about her life at F.U.N. Mrs. Twombly and the bus driver both stop by at the same convenience store but don't notice the other as a truck pulls up between them as they enter, blocking each other from view. In the convenience store, Blythe notices Mrs. Twombly and the pets from the corner of their eye, but they disappear behind a shelf by the time she looks, unable to hear Mrs. Twombly because of the music in her headphones.
Blythe arrives at The Littlest Pet Shop and finds out from Madison that Mrs. Twombly and the pets had left for F.U.N. By then, Mrs. Twombly has already reached F.U.N. and finds out the pickup request was phony. Roger meets up with Mrs. Twombly and tells her he already did his own searching, having found out that Blythe returned to Downtown City. Blythe gets a ride on the Sweet Delights food truck to head back to F.U.N. while Mrs. Twombly brings Roger on board the Littlest Pet Shuttle. They both once again stop at the convenience store, Mrs. Twombly because she wants to stretch and Blythe because Youngmee needs the restroom. The two parties at last meet up and are overjoyed to see each other. Blythe explains her situation and asks Roger if it's okay to withdraw from fashion camp, and Roger says yes. The pets run up to Blythe and get to spend the time with Blythe they didn't get to have all summer long.
This episode contains examples of (YMMV entries go here):
- Actor Allusion: Blythe makes a friend at Fashion University North. Naturally, she has to share a voice actor with this series's sister show's fashion-oriented character.
- An Aesop: Where you go might not turn out to be what you expected it to be.
- All There in the Script: Mr. Bromidic's name, as well as the Plaid Monster.
- Artistic License History: Coal tar dye is actually known as aniline as a group or mauveine, fuchsine, safranine, or induline depending on its color. Also, all of these shades were invented in the 1850s, long before Mr. Bromidic's "early 1900s." What he's actually talking about is indanthrene, which, while it sees use in coloring clothes, is more commonly used in paints and was patented in the early 1900s. Its production is also totally unrelated to coal tar.
- Blatant Lies: Roger denies anything has gone wrong in the kitchen when speaking with Blythe at the beginning of the episode. See "Lethal Chef" below.
- Call-Back: Sunil discusses the events of "Gailbreak!" with the other pets.
- Catapult Nightmare: Blythe gets one on the bus.
- Conspicuous CG: The pet door in the day camp room, the Littlest Pet Shuttle, and F.U.N.'s bus zooming down the road.
- Continuity Nod: Blythe keeps the painting Minka made in "Summertime Blues" in her room.
- Cool Car: Mrs. Twombly's Littlest Pet Shuttle, which shares the "LPS" initials with the shop.
- Dark Reprise: "F.U.N. Song" begins via a description of how happy Blythe is at Fashion University North. By Act 3, however, Blythe gets a musical nightmare where the song, using much of the same lyrics, are used to describe how miserable she's become.
- Disney Acid Sequence: Blythe's nightmare on the bus.
- The Ditz: Madison has apparently forgotten who Blythe is. Twice.
- Gone Horribly Right: Blythe gets to visit a place where she can indulge in fashion every waking minute. Before long, she realizes she's unable to do anything else and grows sick of designing clothes.
- Hypochondria / Sequel Escalation: Madison's hypochondria has escalated from an oxygen mask in "Summertime Blues" to a haz-mat helmet by the beginning of this episode. Her leitmotif uses a theremin to emphasize her weirdness.
- Ironic Name: F.U.N. has become less than fun for Blythe.
- Lampshade Hanging: Sunil is amazed at how Russell can use a full-sized keyboard.
- Lethal Chef: Roger's toaster behind him catches on fire and spews out a lot of smoke as he's speaking to Blythe over their computers. Apparently, this is not the first time it's happened.Roger: I am NOT letting another toaster go up in smoke!
- Multi-Part Episode: With "Summertime Blues," of course.
- My Friends... and Zoidberg: "At the day camp, where there's a funny skunk and a handsome mongoose."
- Offstage Waiting Room: Invoked. While Blythe is honing her fashion skills at F.U.N., the other characters' plot gets started because they've spent all summer doing nothing fulfilling.

- Waking Non SequiturBlythe: The plaid monster's gonna get me!
- Wanting Is Better Than Having: Blythe realizes this soon enough when she finds out all the students at F.U.N. only care about fashion and nothing else, and becomes bored.
- What Happened to the Mouse?: All we see of Jasper and Sue is the photograph Jasper sent to Blythe. How they would react to Blythe's return is never explained. In addition, viewers who didn't see "Summertime Blues" would have no context to this scene.
- We're not sure what became of Blythe's camp mates after she decides to leave.
- Zombie Gait: The students in Blythe's nightmare.
