The episode opens with a clip of Treasure Hunters, where the host, Riley Robinson, heads to the Littlest Pet Shop in search of a treasure chest buried underneath the building. His crew barge into the pet shop without warning, and a startled Blythe tries to find a place to sit down and take it all in. After the producer denies her any chair in the front area, Blythe retreats to the day camp room and lets the pets know the Treasure Hunters crew is in the shop. Zoe and Vinnie dress up like pirates, but before they can do anything, Pepper tells them that the show is a nonfiction series about finding treasure. Mrs. Twombly makes some tea for all of the guests in the room, but she is unable to converse with anybody except Riley, who accepts her tea. He takes a sip of it but has to put it down when the camera starts rolling.
Riley, for the show, explains what happened at the Littlest Pet Shop location over a century ago, which was still a forest: Henrietta Twombly, an ancestor of the modern-day Anna Twombly, was rumored to be able to talk to animals. She kept a treasure in a chest at her cabin, which she shared with her animals and told them that they would never have to go hungry again. Peeking in through a window are Whittman and Brittman Biskit, who overhear Henrietta and covet that treasure.
Back in the present, Riley, on camera, follows the directions written on a treasure map he recently found, whose "40 paces" lead to an empty area in the pet shop's central room. Riley's crew immediately gets to work digging a hole in that spot. As they excavate, the pets emerge from their room, where Blythe tells them that the network will likely keep the treasure for itself and that Mrs. Twombly will get none of that. Pepper, outraged, takes the treasure map and lets the other pets see it, where everyone is shocked except Vinnie.
In the past, when Henrietta leaves the cabin, Whittman and Brittman attempt to sneak in and get the treasure, but Monkey traps them with the windowsill while the other pets except Dog scramble out with the chest. They bury it in a meadow nearby and cover it with a pile of leaves as Dog barks incessantly at Whittman and Brittman to stall them. Brittman slams the door on Dog but is almost immediately greeted by Sheriff Blythe, who ejects them from the premises. Watching from a distance are Henrietta's animal companions, where Hedgehog draws up the treasure map. In the present, Russell confirms this by using one of his spikes as a reference and concludes that the 40 paces must be hedgehog-sized, which instead leads to the building's back alley. Blythe discovers a manhole made by "Biskit Brothers Construction," and Sunil and Russell head into the sewers.
By the time Henrietta returns to her cabin, Whittman and Brittman have bought all of the land around the cabin and have begun to set up buildings around the area, including the land the tree Henrietta's animals used to live in. Henrietta returns to her cabin as the Biskit Brothers attempt to find the treasure by searching underneath the cabin.
Sunil and Russell emerge empty-handed, but Blythe and the pets overhear Riley exclaim in joy. They rush over to the front to see Mrs. Twombly has found an old box containing Biskit Brothers Construction blueprints for the building Sweet Delights is currently in detailing a secret room. Riley barges into Sweet Delights and peels back some wallpaper and at once finds the Biskit Brothers' "B" hand-engraved in the wall.
Eventually, Whittman and Brittman recover the treasure chest, and in pursuit by Sheriff Blythe, run into an adjacent building and hide it within a hole in the wall. Brittman splashes some mortar on the wall and etches their signature "B" on it as a marker.
Riley smashes a hole in the wall and climbs inside, only to find nothing inside. The pets notice paw prints on the floor, however, which Pepper identifies as that of a skunk. It turns out that Henrietta's animals caught Whittman and Brittman discussing the secret compartment, and Hedgehog creates a hole on the back of the building. As they carry the treasure out, the Biskit Brothers spot them and give chase, though the animals eventually lose them.
Blythe and the pets return to the Littlest Pet Shop and see Riley having an argument with his crew about their failure to find the treasure. Blythe distracts the crew by claiming to have found a lead while Pepper connects the cabin's old photograph and the blueprints together to figure out the location of the tree the animals once lived in. Pepper concludes it's the dumbwaiter, and all seven pets hop in. Along the way, Penny Ling loses her grip, exhausted having to carry everyone up, and they fall down the shaft, crashing through the bottom and finding themselves in an old mine with the treasure right in front of them.
Whittman sees Skunk's tail in the hollow tree, so Brittman takes a nearby saw and, with Whittman's help, cuts it down. The tree lands on the cabin, destroying it. As they reach in for the treasure, however, Sheriff Blythe handcuffs them. Henrietta arrives and asks Blythe to let them go—so that she can force them to build her an animal feed shop where the cabin once stood.
Blythe hears the pets' cries for help from the dumbwaiter shaft and, with Riley's help, gets them back up, along with the treasure chest. Riley opens it, only to see a big pile of pet kibble inside. Frustrated at the lack of anything of monetary value, he and the crew storm out of the shop. Mrs. Twombly, however, finds a book of Henrietta's recipes within the kibble and takes it for inspirations as the pets eat their way through the kibble.
This episode contains examples of (YMMV entries go here):
- Anachronic Order: The episode is told from both the present and a century ago. Plot points are revealed in one time period that become significant in the other.
- Anachronism Stew: The flashbacks have little concern as to how characters are dressed, as long as they are associated with the American frontier. They also speak with a mix of historical and modern jargon. Mongoose keeps Sunil's Indian accent despite there being absolutely no reason why he should have one.
- Bad "Bad Acting": Zoe trying to act like a pirate.
- Bat Deduction: According to Russell, because the map has a triangle that's the exact outline of a hedgehog spike, it must mean it was drawn by a hedgehog. He is absolutely right.
- Buffy Speak: According to Pepper, a unit above doubloons is "triploons."
- By Wall That Is Holey: Brittman and Whittman throw down several walls to stop the pets in the flashback from taking the treasure and hiding it. It doesn't do anything to slow them down, however.
- Call-Back: After a brief moment of getting over her fear of the camera in "Terriers & Tiaras" and "The Nest Hats Craze!," Blythe seems back to being nervous in front of one again.
- This is the second time Blythe finds herself in the middle of a reality show, the first being Terriers & Tiaras. This time, she works against the crew, instead attempting to get to the treasure before Riley. It even comes complete with another Take That! (see below).
- Card-Carrying Villain: Brittman talks about stealing treasure in front of Dog and is fairly transparent to Henrietta about their intentions.
- Continuity Nod: The pets in the past seem to love to shower Henrietta with praise in a similar way Anna in the present imagines the pets to do in "Pawlm Reading."
- The back alley's arched window Sunil and Vinnie used attempted to enter the shop at night in "Eight Arms to Hold You" is visible when Blythe and the others follow Russell.
- This episode marks the third time in the series a hedgehog has done a Spin Dash at the Biskit Twins (albeit this time with ancestors), after "Blythe's Big Adventure Part 2" and "Trading Places."
- Deliberately Monochrome: The past is depicted desaturated and with heavy sepia. (See the page image for the result.)
- Documentary Episode: Though not about the full cast, just about the mysterious treasure connected to the Twombly family.
- A Dog Named "Dog": Literally so with Henrietta's dog. The woodland animals share this distinction too with Hedgehog, Skunk, Monkey, Panda, Mongoose, and Gecko.
- Flashback: Makes up the B-story.
- Flashback Effects: See Deliberately Monochrome above.
- Foregone Conclusion: The urban setting of this series indicates that Biskit Brothers Construction ultimately dramatically increased their power over the region, though Whittman and Brittman are unable to obtain Henrietta's treasure.
- Foreshadowing: Although the Cold Open depicts Treasure Hunters as a documentary series (and more specifically an investigation series), Pepper labels Treasure Hunters as reality television. This is a tip-off that Treasure Hunters may not be as informative as it pretends to be. Indeed, the show seems to exist to allow the network to get ahold of valuable items under the guise of a TV show.
- Identical Grandson\/Generation Xerox: Applied to every single ancestor shown in the flashback. Played for Laughs with Whittman and Brittman, who are essentially Whittany and Brittany with handlebar mustaches, and Blythe's ancestor, also named Blythe and seems to have become the local sheriff at her age.
- Hair Decorations: On the Biskit Brothers' heads.
- Improbable Age: Sheriff Blythe, a teenager.
- Lampshade Hanging: In the final shot, Pepper points out that the pets are eating hundred-year-old pet kibble. Russell doesn't mind, and they all continue eating.
- The Leader: Russell steps down from that role in this episode to allow Pepper to take command of the search.
- Like Is, Like, a Comma: The turn-of-the-century setting doesn't seem to stop Whittman and Brittman from talking like valley girls, only with exaggerated time-appropriate dialect sprinkled in.Whittman: I say, Brittman, talking to the animals that Twombly is, like, totally off her rocker.Brittman: Positively, like, rockerless. As if they could understand her.
- Misplaced Wildlife: Hedgehogs, pandas, and mongooses are not native to North America.
- Multiple-Choice Past: Though not via the flashbacks. Pepper states that Treasure Hunters is her favorite show, though in "Lotsa Luck," Pepper is depicted watching That's My Orangutan almost religiously. It is possible, however, that Pepper enjoys Treasure Hunters even more, with That's My Orangutan as an inspiration for her comedy; or that she turned to Treasure Hunters after That's My Orangutan was canceled.
- No Celebrities Were Harmed: Riley is based off of the late Steve Irwin in voice, demeanor, and appearance, though searching for treasure to film rather than exotic animals.
- Non-Answer: When Riley asks Mrs. Twombly about when the building was made, she can only confirm it was either the 19th century or the 20th century.
Pepper: Buttercream! Did you see a crazy Australian guy run by with a film crew?Buttercream: Did he have fancy-antsy yellow-fancy ears and a splooshy-mooshyriffic mermaid tail and a purse bo-burse banana-fo-first that was all wrong for him?Pepper: NoButtercream: (points to her right) He went that way.
- Buttercream describes a completely inaccurate description of Riley Robinson. When Pepper says he's not like that, she points the way.
- Only Sane Man: Blythe is the only one concerned about the TV crew digging a hole in the Littlest Pet Shop floor.
- Recurring Extra: Many of the crew for Treasure Hunters seem to be the same people as were seen in Shake-A-Leg, Shahrukh's crew, and Terriers & Tiaras. The producer also shows up in "The Nest Hats Craze!" as Blythe's assistant.
- Running Gag: The Treasure Hunters crew keep causing property damage wherever they go with no one concerned except Blythe. Eventually, the pets break the dumbwaiter and its shaft as well. No explanation is given as to who will be paying for repairs.
- Starting from the middle of Act 2, everyone and everything seems to keep tracking footprints in the concrete.
- Scooby-Dooby Doors: Used in Act 3 with Henrietta's cabin.
- Settling the Frontier: The most likely setting of the flashback, though it seems to be transitioning from wilderness to an area of permanent settlement.
- Shout-Out: Henrietta's treasure chest is depicted with glowing contents, much like in Pulp Fiction.
- Riley tears down the wall with a sledgehammer much like Robert Irvine in Restaurant: Impossible.
- Show Within a Show: Treasure Hunters.
- Take That!: Pepper inadvertently provides a criticism of reality shows:Pepper: Instead of getting actors to pretend stuff, they get regular people to pretend stuff!
