Fans of Undertale, the quirky indie RPG from Toby Fox, had plenty to buzz about back in September 2021. Good Smile Company, the renowned figure manufacturer known for its adorable Nendoroid line, announced that the skeleton brothers Sans and Papyrus would be getting their own figurines for sale in the U.S. The company shared digital sketches of the duo in the signature Nendoroid style on Twitter, promising more details soon. For a game that thrives on memorable characters, this was a big deal—and it still resonates with collectors in 2026.

Sans and Papyrus are two of the most beloved characters from Undertale, a smash-hit indie game that introduced dozens of colorful personalities. The humorous skeleton brothers—Sans with his laid-back, pun-loving demeanor and Papyrus with his energetic, spaghetti-cooking enthusiasm—quickly became fan favorites. They also appeared in Deltarune Chapter 1, and fans expect them to show up in future chapters. The Nendoroid announcement was a natural fit, given Good Smile Company's track record of turning iconic anime, film, and video game characters into collectible figures. Papyrus and Sans have undeniable crossover appeal; Sans even made a surprise appearance in AEW thanks to wrestler Kenny Omega, who used the character's theme "Megalovania" as his entrance music.

At the time of the announcement, Toby Fox was gearing up for a special Deltarune Chapter 1 stream on Undertale's birthday, September 15th, broadcast on YouTube at 7 p.m. ET / 4 p.m. PT. The creator planned to provide commentary via text-to-chat alongside three employees from Fangamer, Undertale's development company. Speculation ran wild that Fox and company might shadow-drop Deltarune Chapter 2 during the stream to commemorate the occasion. After all, Deltarune Chapter 1 had released online back in 2018, and aside from merchandise announcements and the occasional screenshot, the developer had yet to expand upon the story of Kris, Susie, and Ralsei. Fox had originally said the second chapter would likely release before 2020 ended, but that didn't happen. Fans were hungry for news, and the stream seemed like the perfect moment.

Ahead of the stream, Fox also shared pictures of new Undertale stickers that fans could purchase. These featured Papyrus and Sans, along with Frisk the human and the Annoying Dog. The stickers were a small but welcome treat for a community that had been waiting patiently for more content. Here's a quick look at the characters included:

• 🦴 Sans – The pun-loving skeleton with a mysterious past.

• 🍝 Papyrus – The aspiring Royal Guardsman who loves spaghetti.

• 🗡️ Frisk – The silent human protagonist of Undertale.

• 🐶 Annoying Dog – The mischievous canine that steals everything.

Meanwhile, questions about Deltarune Chapter 2 lingered. Since Chapter 1's release, fans had also wondered whether an Undertale 2 might ever happen. Fox has described mixed emotions about the first game's wild success, and portions of the fanbase have proven problematic at times—overreacting to people who don't enjoy the game. So it seemed more likely that fans would hear about Deltarune's future rather than get an answer about Undertale 2. The stream promised to address some of that speculation.

Fast forward to 2026, and the landscape looks different. Deltarune Chapter 2 did eventually release in late 2021, satisfying fans who had waited years for the continuation. The Sans and Papyrus Nendoroids have since hit shelves and become sought-after collectibles among Undertale enthusiasts. Good Smile Company's initial sketches turned into full-fledged figures, complete with interchangeable parts and the signature Nendoroid charm. For those who missed the initial announcement, the figures are now a staple in many fan collections. The Undertale stickers also remain popular, and the community continues to celebrate the game's quirky humor and emotional depth.

So what's next? As of 2026, Deltarune Chapter 3 is in development, and Toby Fox has teased more adventures for Kris and the gang. The Nendoroid line might expand to other characters—perhaps Susie or Ralsei—but nothing has been confirmed. For now, collectors can enjoy the skeleton brothers in adorable figure form. Whether you're a longtime fan or a newcomer, these Nendoroids capture the spirit of Undertale: charming, funny, and a little bit weird. Some might say these announcements fill them with determination. 😊
