The first drop week of September is here, and the theme of this week's new blind box releases (September 2026) is refreshingly clear: things you can actually carry. A wearable Baby Three backpack leads the pack, LuLu the Piggy shrinks down to mini scale, Hello Kitty gets lop ears, and a brand-new fox fairy series lands at a price that makes it the cheapest full set in the store right now. Here's everything that arrived at DidaPop between August 25 and September 1, with prices, set options, and honest notes on what's already running low.
Hero drop: Baby Three School Backpack Collection Series Blind Box
Baby Three has done phone bags, zipper pouches, and lanyards, but the School Backpack Collection is the first time the character has become a full, wearable backpack. Each piece is a plush Baby Three with a working zip compartment and straps, sized for a kid's day out or for adults who want the most unmissable bag charm on the train. It arrives right as school starts, which is no accident. If you read our back-to-school backpack charm guide, this is the maximalist version of that idea: the charm is the bag.
Pricing: $50.99 for one backpack without the retail box, $99.00 for two (save $15), or $118.00 for one with the original box if you're gifting or keeping it sealed. Stock note: 16 no-box units, 6 two-packs and only 3 boxed units were left at the time of writing. The boxed version is the one most likely to disappear first.
LULU THE PIGGY Plaza Mini Series Blind Box
TOYZEROPLUS's canned pig is back, and this time the whole cast has been miniaturised for the Plaza Mini Series. Each box contains two mini figures, which makes it one of the better value-per-figure buys of the week. The Plaza theme puts LuLu into shopping-mall scenes, with the same deadpan expression that made the character the blind box world's comfort mascot (we covered the origin story in our LuLu the Piggy explainer).
Pricing: $10.99 per box (2 pcs) or $126.99 for the 12-box set, which saves $5. This is the best-stocked drop of the week with 35 single boxes and 4 full sets available, so there's no need to panic-buy yet.
Sanrio Hello Kitty Lop Ear Bunny Series Plush Pendant Blind Box
The Lop Ear Bunny series dresses Hello Kitty and friends in floppy-eared bunny costumes, and the long drooping ears are the whole point: they swing when the pendant is clipped to a bag. It's a TOPTOY-made Sanrio release, which matters if you've read our Sanrio blind box guide on why Hello Kitty comes from several different makers. TOPTOY's plush work on Sanrio has been consistently among the softest.
Pricing: $21.99 per pendant (no box) or $169.99 for the 8-piece set, saving $6. Stock note: 9 singles and just 1 full set remain. Sanrio pendant sets at DidaPop have historically sold out within two weeks, so treat the set as a now-or-never.
Little Fox Fairy Under the Shimmering Light Series Blind Box
This is the newest listing of the week (it went live the morning of September 1) and the cheapest way to own a complete set of anything in the store. Little Fox Fairy: Under the Shimmering Light is a small-scale fox character series with a soft, glowing lantern-and-moonlight theme that reads more autumn than summer, which is exactly right for September. Blind boxes come in packs of four, so you're building the set quickly.
Pricing: $8.99 for 4 boxes, or $25.99 for the full 12-box set. Only 6 four-packs and 3 full sets were listed at launch, so this one is genuinely limited.
POP MART Pucky Close For Today Plush Series
Pucky is one of POP MART's longest-running elf characters, and Close For Today is its plush-format series built around the feeling of a shop shutting its doors for the night. POP MART's own half-year results, published on August 20, showed plush now makes up well over half of the company's revenue, and Pucky is one of the older IPs that has quietly benefited from that shift. Each plush comes without a box in the standard variant.
Pricing: $24.99 per plush (no box) or $143.99 for the 6-piece set, saving $6. 12 singles and 1 set remain.
Also new this week
Rilakkuma Sweet Heart Tube Keychain Series Blind Box
A pocket-money pick at $4.99 per box. The Sweet Heart Tube Keychain puts Rilakkuma and friends into little heart-shaped tubes you can hang from a zip. Seven singles remain and the 12-box set has already sold out.
Evelynna Doppleganger Series MJD Blind Box
For the doll collectors: the Evelynna Doppleganger MJD is a poseable mini-jointed doll series built around mirror-image twin designs. $28.99 per box or $169.99 for the 6-box set (only one set left). If you're new to the format, our BJD blind box explainer covers what to expect.
ALIEN STAGE AAHS Series Chuichui Style Plush
The ALIEN STAGE AAHS plush ($22.99) is down to a single unit as of this writing, and the Sooya Studio x M Stand coffee-themed bean series that landed on August 30 sold out entirely within 48 hours. Both are proof that fandom-driven releases move faster than mainstream ones.
Which new release should you buy first?
If you want the piece people will ask about, it's the Baby Three backpack, and the boxed version is the scarce one. If you want value, the LuLu Plaza Minis give you two figures for $10.99 and are well stocked. If you're set-building on a budget, the Little Fox Fairy full set at $25.99 is hard to argue with. And if you're a Sanrio pendant collector, the single remaining Lop Ear Bunny set is the one to grab before it goes.
