As Sunil peers into an ant farm wondering what it is, Blythe passes by and identifies it as such. As soon as he realizes it's meant to hold insects, Sunil scrams and hides beneath Pepper's tail, prompting Pepper to force Sunil back into the open. Sunil tells the other pets that he's afraid of insects of every kind, which Blythe overhear and points out that the farm is empty and that there's nothing to worry about—until Mrs. Twombly realizes the box of bugs has a hole in it and its inhabitants have escaped. The bugs all make their way onto Sunil and causes him to shriek at such a high pitch that the nearby dogs go berserk, including Zoe.
By the time Jasper comes by to visit, the dogs have already wrecked the main room and left. Jasper provides not-so-helpful commentary he takes from his comic book, Super Sam, provoking Blythe to hand him a broom and make him help clean up. Mrs. Twombly finds Sunil hiding in the ant farm and shakes him out. Sunil sulks to Penny Ling, who tries in vain to help him deal with being afraid, as she has experience in it herself. Sunil looks for some other place to hide, and as Penny continues to help with cleaning, she finds Jasper's Super Sam comic book that fell to the floor.
Jasper tells Blythe that he needs to go meet up with his mom for lunch and leaves the shop, forgetting his comic book, which reminds Blythe to meet up with Youngmee and her aunt Christie to help with their Sweet Delights truck. Russell steps up, saying that he did his own thinking and Web-searching for good food truck locations around the city, convincing Blythe to take him along. Russell subsequently spends his time on the Sweet Delights truck scarfing down cupcakes in front of Sugar Sprinkles.
Penny witnesses Sunil get scared by a dust bunny and cooks up the myth of El Cobra Cobra, a superhero with the combined strengths of bugs, and that the bugs develop an affinity for Sunil because he is their chosen leader. Sunil does not buy that story, however, and walks away, although Penny has already planned for this and starts working on something.
Russell provides Blythe with a bogus tip that an upcoming block is a good place for food trucks, as many people walk by there and no other food trucks have claimed it. However, the moment that Christie starts pulling over, a sandwich truck the length of the entire block barges in and claims the location. As they confront the driver of the sandwich truck, they discover Monban in the passenger's seat. After witnessing a curious customer stomp away highly dissatisfied, Blythe discovers Whittany and Brittany Biskit in the front commanding the operation. Blythe tries to ask them to move the truck, but naturally, they refuse. The Biskit Twins give a spiel that their strategy is not about the type of food they sell, but to eliminate the competition by taking up all of the food truck space in Downtown City. Soon enough, a police officer comes by and gives the Sweet Delights truck a parking violation ticket. Russell attempts to stop him to no avail, but the officer's dog gives Russell the advice of arriving at exactly 9:30 AM to ensure they get the spot. Anytime before that, and the officer will issue a ticket (pointing out that he really loves to issue tickets), and after that, other food trucks will crowd the block's curbside.
Back at the Littlest Pet Shop, Russell relays this information to Blythe, and as she heads next door to tell Youngmee, Penny requests for Blythe to design a superhero suit for Sunil, as well as one for herself to be El Cobra Cobra's sidekick. When Blythe finishes and puts it in a box, Penny slides it out in front of Sunil, tripping him, She gets him into El Cobra Cobra suit and puts on her suit as Pandamonium. The other pets, in on the act, stage Pepper in distress to make him think he flew over to rescue her. Convinced that he is now a superhero, Sunil dashes out the door to look for pets in trouble, to the worry of the other pets.
At 9:29 AM the following morning, Blythe gives the signal to head to the curb. As Christie pulls out, Blythe spots the sandwich truck right behind them and gives chase. The sandwich truck gets stuck behind some slow drivers, so Monban recalculates an alternate route and reprograms the traffic lights to favor the sandwich truck, getting Christie stuck at a red light long enough for the sandwich truck to beat Sweet Delights to the curb. As Christie waits, Russell sees the police officer helping an old lady and her dog, which gives Russell an idea.
Sunil soon finds a chinchilla on the floor of the Littlest Pet Shop trying to get a chew toy on a top shelf. Sunil, believing he can walk on walls due to Penny's assistance, heads up the shelf and retrieves it. With his head in the clouds, Sunil runs about helping out visiting pets in any way he can, obliviously requiring the help of Minka and Vinnie as well. Heading to Blythe's bedroom, which he calls his secret lair, he sees Mary Frances tangling a woman in his leash. Sunil leaps down from the open window, but Penny catches him with a hook and pulls him back up. She confesses to Sunil that he has no powers and that it was all made up to try to build some confidence in him. In response, Sunil throws down his domino mask and stomps away.
Blythe comes back to the shop with a plan she discussed with Russell to beat the Biskit Twins, though Sunil sits in a corner, refusing to participate. Russell's idea is that Monban will cut off drivers and manipulate traffic lights but must stop for pedestrians. With Sugar Sprinkles keeping track of the Sweet Delights truck's location and that of the sandwich truck when it's in sight, Blythe strategically heads towards pedestrian crossing zones and walks across as slowly as possible to slow down the sandwich truck. As it becomes clear Blythe will not let the sandwich truck reach its destination by 9:30, Brittany instructs Monban to turn around, then squirts orange soda pop at Blythe as she walks by the nozzle. The sticky liquid keeps Blythe and all of the accompanying pets immobilized, allowing the Biskit Twins an unobstructed path to the block.
When everyone else believes all hope is lost, Sunil realizes he has a unique talent: Sunil asks Penny to scare him, and after a bit of hesitation, she roars at him, causing him to emit another supersonic shriek that sends a large pack of dogs scampering in front of the sandwich truck, stopping it just long enough for the Sweet Delights truck to beat it to the curb.
The Sweet Delights truck proves a success at this location, and Penny points out that Sunil was brave enough to not give up and try something. Penny suggests the superhero name Supersonic Sunil and that the two of them may want to try the hero gig some other time.
This episode contains examples of (YMMV entries go here):
- 2D Visuals, 3D Effects: As vehicles are depicted as turning in this episode, they are rendered in cel-shaded CG.
- Abnormal Ammo: The Biskit Twins weaponize their truck's orange soda pop to restrain Blythe and her animals.
- Artificial Stupidity: Whittany and Brittany seem to have poorly programmed their sandwich truck's dispensing mechanism. It fires a sandwich at the customer's mouth, sprays him or her with orange soda pop, then dispenses a cup and chucks it at the customer.
- Blythe does call attention to it but the twins freely admit they don't care as long as they get some form of business. Good service apparently not being a concern to them.
- Artistic License – Biology: Some of the bugs meant for the insect farm are not insects, though they are all arthropods.
- Automated Automobiles: Sort of—Monban is there in the driver's seat, but he is an automaton using the sandwich truck as an extension of himself.
- Bad "Bad Acting": Pepper screaming for help.
- Bragging Theme Tune: "El Cobra Cobra." The lyrics give off this vibe without ever having to explain what El Cobra Cobra is capable of.
- Call-Back: This episode follows up on the events of "Sweet (Truck) Ride," and subsequently, the return of Sugar Sprinkles. Even the traffic cop from that episode returns.
- Penny's ability to come up with tall tales on the spot was last used and discovered in "So Interesting."
- Monban reappears in this episode. While knowledge of "Gailbreak!" is not required to understand this episode, familiarity with "Gailbreak!" makes Monban's first scene a tip-off to who is in charge of the sandwich food limousine.
- Chase Scene: Twice in this episode, both between the Sweet Delights truck and the Biskit Twins' sandwich truck.
- Chekhov's Gun: The sandwich truck's means of beverage dispensing, though a villainous example.
- Sunil's supersonic screaming.
- The Chosen One: Penny's backstory for El Cobra Cobra involves the insect picking someone to be their leader.
- Compressed Vice: Sunil never exhibited any fear of insects prior to this episode, which is all the more glaring as his best friend Vinnie loves eating flies. For instance, Sunil does not feel disturbed at all by the Insect Channel in the previous episode. That being said, he did make mention of being "scared of creatures with six or more legs" in "Heart of Parkness."
- Continuity Nod: Pepper yells into Sunil's face in a manner similar to the way she yells into Blythe's face in "Blythe's Big Adventure Part 1."
- Zoe is seen chewing on her hot dog chew toy, as seen in "Pawlm Reading" and "To Paris with Zoe."
- This is the second time Sunil lists random things he's afraid of. Oddly, there is no overlap between this list ("darkness, bright sunshine, paper clips, and those little photo display cubes") and the one in "Heart of Parkness" ("creatures with six or more legs, loud noises, curtains, avocados, and quiet jazz music").
- The Sweet Delights truck seems prone to chases, as seen in "Sweet (Truck) Ride."
- After a 9-episode absence, Buttercream reappears with a non-speaking cameo role in Sunil's help-montage.
- Mary Frances has a new owner.
- Russell makes another plan requiring everyone's talents to stop the Biskit Twins and Monban, just as he did in "Gailbreak!" Again, Sunil's involvement is crucial to it working.
- Creepy Centipedes / Creepy Cockroach: Crawling all over Sunil in the Cold Open.
- Drives Like Crazy: Monban, the most reckless robot driver.
- "Everybody Laughs" Ending
- Everything Is Online: Monban is able to change traffic lights remotely.
- Exactly What It Says on the Tin: Flying like a fly is one of El Cobra-cabra's abilities.
- Get A Hold Of Yourself Man: Said almost word-for-word by Pepper to Sunil in the cold open.
- Gone Horribly Right: Penny's scheme to instill some confidence into Sunil causes him to seek out danger.
- Heroic Build: Sunil in the song "El Cobra Cobra." Subverted—it's actually a cardboard cutout of rippling muscles.
- Hypercompetent Sidekick: Pandamonium.
- My Friends... and Zoidberg: Whenever the self-imposed theme song to Sunil comes up, it always ends with a quick "And Sidekick Panda" with Penny having to keep correcting the name.
- Mr. Imagination: Sunil has shades of this, just like his comrades—though he apparently lets his imagination overwhelm him as he sees photographs in glass cubes as if they're trapped in them.
- Paper Tiger: Sunil soon becomes one when he's convinced he's a superhero.
- Prehensile Tail: Pepper, at one point, wraps her tail around a tube to hold on to it.
- Power Incontinence: Sunil thinks that his inability to fly comes from him using his powers too much.
- Running Gag: Sunil is unable to remember Penny's sidekick name, always calling her "Sidekick Panda."
- The superhero theme song likewise keeps calling her by that name.
- Screams Like a Little Girl: Sunil's last shriek when he finds the bugs on him. It becomes so high pitched that only dogs can hear it. See Chekhov's Gun above.
- Shout-Out: El Cobra Cobra's name is based on the legend of El Chubacabra.
- Penny asks Sunil if he's thinking what she's thinking, to which Sunil answers with a Non Sequitur.
- The traffic cop is depicted giving out traffic tickets in the morning in a manner similar to Daffy Duck.
- The visual sound effects are based on Adam West's Batman.
- Super Sam shares his name with another expy of Superman from The Fairly OddParents!, and there's also an amalgamated parody of Superman and Uncle Sam from El Chapulín Colorado.
- Silent Whisper: Russell's "tips" to Blythe.
- Small Role, Big Impact: Jasper does exactly one plot-significant thing, which is leaving his comic book in the Littlest Pet Shop. This would kick off the B-story and (very) indirectly allow Christie to beat Monban to the curbside.
- Squashed Flat: Sunil inflicts it on himself by hiding in the ant farm.
- Superheroes Wear Tights: Penny comments when picking up the Super Sam comic book if his outfit feels restrictive.
- That Makes Me Feel Angry: While it's part of Blythe's acronym-infused speech, it is still redundant to laugh, then say "LOL."
- The Watson: Sugar Sprinkles's main narrative purpose, at least until the second pursuit, is to provide someone for Russell to talk to when he can't speak to Blythe.
- Written Sound Effect: During "El Cobra Cobra."
