A Viral Sensation Turned Retail Juggernaut: RMS USA’s Mystery Dumpling Continues Its Sell-Out Streak

NORTH ANDOVER, Mass.--(BUSINESS WIRE)--RMS USA today announced continued momentum for its Mystery Squishy Dumpling phenomenon, a collectible squishy that first took off last year and has since evolved into an ongoing social media craze, with fans racing to find rare variants and pouncing on every restock the moment it drops.

In 2025, The Toy Book reported RMS USA’s Squishy Bun Mystery Dumplings had in its first phase attracted more than 500 million TikTok viewers, driven by influencer unboxings and the hunt for Ultra-Rare dumplings. That viral momentum has not slowed into 2026. RMS USA’s own brand messaging calls the Squishy Dumpling “the internet’s favorite squeeze,” positioning it as the original squish sensation everyone is talking about.

​The hype is real, and it keeps converting to sell-outs

Retail demand continues to surge across channels, with “can’t find it” posts and rapid sell-through stories becoming a recurring theme in the fan community. Shoppers and employees describe the Mystery Dumplings selling out instantly and customers repeatedly calling stores asking when more will arrive. Another thread describes stores selling through stock “within the hour” they are put out.

​A modern collectible built for social sharing

​The Mystery Squishy Dumpling has become a staple of short-form content: unboxings, “rare find” reactions, squeeze ASMR, and collector call-outs. The 2025 frenzy was amplified by high-reach creators, and continues today with some of social media’s biggest toy influencers across all platforms.

“Watching this go from a breakout hit last year to a sustained, viral, always-on demand engine has been incredible,” said Zack Farber, CEO at RMS USA. “It is the kind of product that lives on camera and in-hand. Every restock becomes an event.”

​What’s next

RMS USA will continue supporting retail partners and planned replenishment cycles as demand remains strong and availability continues to turn quickly.

The Dumpling era is just getting started. RMS USA is broadening the line into new categories and preparing a series of highly anticipated drops set to roll out later this year.
