New blind box releases September 2026 – Spider-Man Brand New Day plush keychain blind box at DidaPop

The new blind box releases this week at DidaPop lean hard into characters you already know. A Marvel movie tie-in leads the drop, the internet's favorite Dutch bunny shows up in a tiny raincoat, and LuLu the Piggy wanders into a ghost festival wearing a bridal veil. Add a sold-out-everywhere WAKUKU restock down to its last two pieces and a pair of spooky-season plush lines, and this is one of the most license-heavy weeks we've had all September. Here's everything that landed, with prices, set options, and what's already running low.

The Hero Drop: Spider-Man Brand New Day Plush Keychain Collection

Spider-Man Brand New Day plush keychain blind box collection at DidaPop

With Spider-Man: Brand New Day still riding its box-office wave from this summer's theatrical run, the merch cycle has officially reached the blind box aisle. The Spider-Man Brand New Day Plush Keychain Collection turns the wall-crawler into soft, clip-on form — eight designs per set, built to hang off a backpack strap or bag handle rather than sit in a cabinet.

A single blind pull is $17.99, and a full 8-piece set is $138.99 (which knocks $5 off buying singles). Fair warning: as of this writing there is exactly one full set left, and superhero licenses at this price point rarely sit around. If you want a guaranteed complete lineup rather than gambling on pulls, that set is the move.

Miffy Raincoat Series: The 71-Year-Old Bunny Is Having a Moment

Miffy Raincoat Series plush keychain blind box at DidaPop

If your feed has been full of Miffy lately, you're not imagining it — the character has quietly become one of 2026's biggest crossover stars, with collabs selling out at major coffee chains and mall retailers stocking Miffy bag charms next to their own-brand accessories. The Miffy Raincoat Series Plush Keychain Blind Box catches that wave at exactly the right season: Miffy in tiny rain gear, keychain-sized, ready for fall.

Singles are $14.99, or grab the full 6-piece set for $114.99. Only 3 full sets came in, so set buyers shouldn't wait on this one either.

LULU THE PIGGY Surprise Can 3: A Ghost Festival in a Tin Can

LULU THE PIGGY Surprise Can 3 Series blind box ghost festival edition

TOYZEROPLUS sends its canned pig somewhere unexpected for round three of the Surprise Can line: a ghost festival. One LuLu turns up in a red bridal veil, another wears a Qing official's winged hat and robe — it's equal parts adorable and slightly haunted, which makes it a perfect bridge piece between everyday LuLu collecting and October shelf decor.

The LULU THE PIGGY Surprise Can 3 Series Blind Box is $15.99 per can, or $59.99 for a 4-can set (save $4). If you're new to this character and wondering how these cans fit into the wider lineup, our LuLu the Piggy price guide breaks down every format and what it should cost.

Yuna Petit Wee Ghost: Spooky Season's Softest Entry

Yuna Petit Wee Ghost Series plush blind box

The Yuna Petit Wee Ghost Series Plush Blind Box is spooky the way a nightlight is spooky: vinyl faces with x-stitched eyes and sewn-shut mouths, sunk into long-pile fur. At $14.90 per pull — or $106 for the full 8-piece set, a $13 saving — it's one of the cheapest ways to add something genuinely Halloween-coded to a shelf this year. For the bigger seasonal picture, see our Halloween blind boxes 2026 roundup of what's already selling out.

WAKUKU Addictive Series: Down to the Last Two

WAKUKU Addictive Series blind box plush

WAKUKU keeps getting named as a next-big-thing character, and stock levels here back that up. The WAKUKU Addictive Series Blind Box gives each design a personality rather than a costume — the backing card literally labels them, with Introverted arriving in a black furry hood. At $22.99 per pull, there are only 2 pieces left as this post goes live. This is the one to grab first if it's still showing in stock when you read this.

Also New This Week

Beyond the headliners, four more lines landed: the UUTOY I Need You Series Beans Blind Bag ($18.99 for a 4-piece bag, or $218.99 for the full 12-bag, 48-piece set — only 2 sets in stock); the HypeZizi All Day Vibe Doll Blind Box ($17.99, nearly gone with 4 pieces total remaining); the HUNTER × Beibei Cat Rain Boot Universe Bean ($19.99 per 4-piece bag), a genuine fashion-brand crossover that pairs nicely with Miffy's raincoat energy; and the Sweet Baby Food Keycap Series Blind Box from QUBY at an impulse-friendly $4.99 per keycap.

Which New Release Should You Actually Buy?

If you only pick one: the Spider-Man set for license collectors, the Miffy Raincoat series if you're charm-focused, and the Wee Ghost plush if you're building a Halloween shelf on a budget. Set buyers should move fastest — the Spider-Man collection, Miffy sets, and WAKUKU singles are all in single-digit stock. Last week's drop coverage is here if you want to catch up on the Jiimo cloud and Nommi izakaya releases, several of which are still available.
