Poppy Playtime: All Experiments Across Every Chapter
Have you ever wondered what really went on behind the colorful walls of Playtime Co.? Today, we’re going to dive into one of the darkest aspects of the game – the experiments.
Let’s take a look at every single experiment conducted at Playtime Co. in Poppy Playtime across all the chapters, from the successful transformations that created iconic characters like Huggy Wuggy to the mysterious failed attempts that were never meant to see the light of day.
All Successful Experiments in Poppy Playtime
Let’s start with the experiments that actually worked – though “success” might not be the best word for what happened to these individuals:

Most Notable Experiments
Experiment 1166: Quinn Navidson (Yarnaby)
Yarnaby’s story is one of the saddest in Playtime Co. He started as Quinn Navidson, a clever orphan who caught Dr. Harley Sawyer’s attention. In August 1990, Quinn became Experiment 1166, turning into a rainbow-yarn-covered lion with a split face hiding jagged teeth. What makes Yarnaby different is his complete obedience – Dr. Sawyer kept him isolated from everyone else, making Yarnaby totally dependent on him. Unlike other monsters who act out of revenge or anger, Yarnaby just follows orders without understanding the harm he’s causing.
Experiment 1170: Huggy Wuggy
Created in 1984, Huggy Wuggy started as Playtime Co.’s friendly mascot. But in 1990, everything changed when he became part of the Bigger Bodies Initiative. As Experiment 1170, he was transformed into the factory’s living security system.
Behind those red lips, he’s got two sets of sharp teeth – one in his mouth and another hidden near his throat like an eel. Those long arms with yellow Velcro hands aren’t for hugging anymore – they’re for catching prey. During the 1995 “Hour of Joy” incident, under the Prototype’s control, Huggy participated in a massacre of company employees. He’s still around in Chapter 4, though pretty beat up, missing part of his left head and his entire left hand.
Experiment 1172: Kissy Missy
Think of Kissy Missy as Huggy Wuggy’s pink counterpart. She went through similar experiments but kept more of her gentle nature. While still transformed into a toy-like creature, she doesn’t show the same aggression as Huggy Wuggy.
Experiment 1322: Doey the Doughman
Doey the Doughman isn’t just one person – he’s actually three different boys merged into Experiment 1322. There’s Matthew (1322C), a kind 15-year-old orphan who looked after other kids; Kevin (1322B), a skilled but aggressive gamer; and Jack (1322A), who tragically fell into a Play-Doh mixer.
Together, they became Doey, who can shape-shift his Play-Doh body at will. He started out protecting other orphans in Safe Haven, but things went wrong during an attack. The trauma triggered all three personalities, with Kevin’s aggressive side taking over. In the end, Doey transformed into a scary reptile with three heads, each representing one of the trapped souls inside him.
Experiment 1354: Dr. Harley Sawyer
Dr. Sawyer is extra interesting because he was actually one of the scientists working at Playtime Co. He ended up becoming part of his own experiments. The transformation was technically successful, but imagine being the doctor who becomes the test subject – pretty creepy, right?
Experiment 1006: The Prototype
The Prototype was one of Playtime Co.’s earliest and most dangerous experiments. What makes it especially creepy is its ability to collect parts from dead toys and add them to itself.
It has mechanical spider-like legs and sharp metallic fingers. In Chapter 4, we learn that the Prototype was actually pretending to be a helpful character named Ollie, using this fake identity to carry out its plans.
It seems especially obsessed with Poppy and has some pretty dark plans for her as we saw at Poppy Playtime Chapter 4 ending. The Prototype is still alive and causing trouble, especially after the events at Safe Haven.
Poppy
Even though she wasn’t listed as a success or failure, Poppy is probably the most important experiment of all. She’s not just another toy – she’s the one who helps us understand what’s really going on at Playtime Co. Her experiment turned her into a doll, but she kept her ability to think and feel, making her different from the others.
All Critters in Poppy Playtime
Playtime Co. created two contrasting lines of animal plushies: the Smiling Critters in Summer 1989 and their darker counterparts, the Nightmare Critters.
While both lines shared similar features like scented plushies and distinctive pendants, they were designed with opposing personalities and aesthetics. The Smiling Critters had toothless, friendly smiles and bright colors, while the Nightmare Critters featured animal-appropriate teeth and darker color schemes.
| Critter Name | Group | Image |
| DogDay | Smiling |  |
| Bobby BearHug | Smiling |  |
| Bubba Bubbaphant | Smiling |  |
| CraftyCorn | Smiling |  |
| Hoppy Hopscotch | Smiling |  |
| KickinChicken | Smiling |  |
| PickyPiggy | Smiling |  |
| CatNap | Smiling | |
| Baba Chops | Nightmare |  |
| Icky Licky | Nightmare | Investigating |
| Rabie Baby | Nightmare | Investigating |
| Allister Gator | Nightmare | Investigating |
| Simon Smoke | Nightmare | Investigating |
| Poe | Nightmare | Investigating |
| Touille | Nightmare | Investigating |
| Maggie Mako | Nightmare | Investigating |
Both toy lines were seen in the game’s story. The Smiling Critters appeared prominently in Chapter 3: “Deep Sleep,” while the Nightmare Critters made their debut in Chapter 4: “Safe Haven.”
Whether you’re deep into Poppy Playtime’s story or just getting started, understanding these experiments helps explain why the game’s world is the way it is. It’s not just about scary toys – it’s about the dark story of how they came to be, and the price paid by those who became part of Playtime Co.’s twisted experiments.
