The animated film with the year's most rewatched soundtrack now has a merchandise catalogue of more than 500 official items — and the ones people actually search for split cleanly in two. Derpy, the tiger, is easy: the official plush is in stock in three currencies. HUNTR/X, the girl group, is hard: all three Mattel singing dolls are sold out at Netflix's own shop. We checked every claim below against the shops' live inventory data today, because this is a catalogue where the picture changes weekly.
Below: what is genuinely in stock and where, the LEGO set that is nine days old, the sold-out list with its one workaround, and how to spot the fakes that have flooded every marketplace.
Derpy: the easy purchase
The tiger is the merchandise programme's anchor, and Netflix's official shop treats him accordingly. The core item — the 10-inch Derpy plush — is stocked on the shop's regional storefronts with local pricing, and all three report availability today:
| Market | Price | Status |
|---|---|---|
| US | $29.99 | In stock |
| UK | £28.00 | In stock |
| AU | A$50.00 | In stock |
Two details worth knowing before you order. First, this plush is Netflix's own product — the vendor of record is Netflix itself, not a toy licensee, which matters when you are comparing against marketplace listings claiming to be "the official one". Second, a good share of the apparel in the same catalogue is print-on-demand: officially licensed, but manufactured after you order, with the backpack listing quoting 10–14 business days before it ships. Official and instant are not the same thing here.
The LEGO set is nine days old
The single freshest item in the entire programme: LEGO 72537, Derpy Tiger and Sussie Bird — 825 pieces, ages 9+, released 1 August 2026 after a June reveal. Brickset's coverage puts the price at $69.99 / £59.99 / A$119.99, and Jay's Brick Blog confirms it is the first set of a full LEGO theme for the film, with more sets planned for 2027.
The build gets the joke right: the tiger's face swaps between two expressions — the goofy grin and a love note on his tongue — and Sussie the bird perches on his head. LEGO's designer describes the eyes as the heart of the character, which anyone who has seen the film will recognise as the correct diagnosis.
If the set matters to you, the timing does too: first sets in a licensed theme are the ones that later trade above retail once the initial run sells through. That is a pattern, not a promise.
HUNTR/X: sold out, with one door open
Here is the part the search traffic is really about. At Netflix's shop, the Mattel singing dolls — Golden Rumi, Golden Mira and Golden Zoey, $32.95 each — are sold out, all three, per the shop's live inventory today. The Fisher-Price Little People Saja Boys set at $32.99 is gone with them.
But sold out at one licensee's shop is not sold out everywhere, and this franchise currently has the clearest example we have seen of that rule: Mattel's own collector storefront still lists substantial stock the aggregator shop does not have. Available there today: the Demon Jinu collector doll at $80, the ramyeon-themed figure three-pack at $50, the Rumi & Jinu two-pack at $44, individual figures at $22, and a Polly Pocket Saja Boys five-pack at $20. The Rumi fashion doll is the one piece sold out on both storefronts.
Mattel's own page also states outright that more drops are coming this year — their words: this is "just the start". Which changes the buying calculus: paying a marketplace scalper for a $32.95 doll makes little sense when the manufacturer is publicly promising more supply.
What is still buyable for Saja Boys fans at Netflix's shop: the Funko blind-box figures at $14.99, the standee set at $44.95, the glassware at $27.95, and the hoodie at $39.95 — all reporting stock today.
The fake problem, and the one check that works
Every marketplace search for this film returns pages of plush that look nearly right and cost slightly less. Unlicensed copies of Derpy specifically are everywhere, and at a distance they photograph identically to the real one.
The check that actually works is not the photo — it is the seller and the vendor name. The official programme runs through a specific, short list of licensees: Netflix's own shop, Mattel (and Fisher-Price), LEGO, Funko, Jazwares (plush and Squishmallows), Hasbro, and a handful of named suppliers inside the Netflix shop catalogue. A plush sold by a marketplace storefront with a generic name, shipping from nowhere in particular, is not from that list no matter what the listing title says.
Price is the second tell, in the unexpected direction: the real Derpy is $29.99. Fakes cluster slightly below real prices, because the copy has to win on something. A "Derpy" at $17 is not a deal.
What we could not verify
In keeping with how we work: the Jazwares plush line (the 18-inch sleeping Derpy, the Squishmallows) and Hasbro's NERF and Furby crossovers are reported by trade press we consider reliable, but we could not load their product pages directly today, so we are not quoting stock or prices for them. Treat those lines as real but check them live. UK trading-standards seizures of counterfeit KPDH goods have been reported; we could not load the original notices, so we note the reports exist without quoting their numbers.
The honest buying order
If you are working down a list, this is ours, on today's stock:
- The Derpy plush at $29.99 / £28 / A$50 — in stock, official, and the film's actual mascot.
- The LEGO set at $69.99 — nine days old, first of its theme, and the best object of the programme.
- Mattel Creations for anything HUNTR/X or Jinu — the collector storefront is where the remaining stock lives, at collector prices.
- Skip resale on the singing dolls. Mattel has publicly promised more 2026 drops; scarcity this early in a programme this large is temporary.
FAQ
Where can I buy the official Derpy plush? Netflix's own shop: $29.99 in the US, £28.00 in the UK, A$50.00 in Australia — all three storefronts report it in stock as of 10 August 2026.
Are the HUNTR/X singing dolls still available? Not at Netflix's shop — Golden Rumi, Mira and Zoey ($32.95 each) are all sold out there. Mattel's own collector storefront still has related stock, including the Demon Jinu doll at $80.
Is there a KPop Demon Hunters LEGO set? Yes — LEGO 72537, Derpy Tiger and Sussie Bird, 825 pieces at $69.99 / £59.99 / A$119.99, released 1 August 2026. It is the first set of a full theme, with more planned for 2027.
Will more merchandise be released? Yes. Mattel's collector page states more drops are coming in 2026 for both HUNTR/X and the Saja Boys, and LEGO has further sets planned for 2027.
How do I spot a fake Derpy plush? Check the seller against the official licensee list — Netflix shop, Mattel, LEGO, Funko, Jazwares, Hasbro — rather than the photos. And be suspicious of prices slightly below the official $29.99; fakes undercut, they don't match.
What Saja Boys merchandise is in stock? At Netflix's shop today: Funko blind-box figures ($14.99), the standee set ($44.95), glassware ($27.95) and the hoodie ($39.95). The Fisher-Price Little People set is sold out.
Is the official apparel made to order? Much of it, yes — listings in the Netflix shop catalogue show print-on-demand vendors, with quoted production times around 10–14 business days before shipping. Licensed, but not fast.
Why is so much sold out if there are 500+ items? The catalogue is broad but the character-specific hero items — the dolls, the Little People set — sell through first. The breadth is in apparel and accessories; the scarcity is concentrated exactly where the search demand is.
