CatNap Overview:
CatNap, aka Experiment 1188 and formerly orphan Theodore Grambell, serves as the main antagonist in Chapter 3: “Deep Sleep.” Designed by Playtime Co. through the Bigger Bodies Initiative, he was once tasked with guarding the Playcare facility using a potent hallucinogenic red gas (“Red Smoke”) to incapacitate children.

His toy form is a purple, wide-grinned, anthropomorphic cat with a crescent-moon pendant—creepy in both appearance and demeanor.

. As players collect batteries and solve puzzles to reroute gas in the Gas Production zone, they’re plagued by CatNap’s hallucinations before facing the final showdown in the Safe Room.

Chapter 3 Finale & Conclusion

• In the climactic boss fight, players overcharge their GrabPack to electrocute CatNap, amplifying the gas, setting him on fire.

• As he collapses, the Prototype’s mechanical hand appears—CatNap momentarily believes he’s being saved, but instead is impaled through the mouth and gruesomely killed. His body is then carried away to presumably fuse with the Prototype’s form.

• In his dying moments, CatNap’s worshipful devotion is brutally betrayed: he expected salvation from his “god,” only to be discarded.

🌌 Thematic Takeaways

• Tragic redemption twisted into worship: CatNap’s arc evolves from a protector to a fallen worshipper whose devotion leads to his demise.

• Prototype’s ruthless nature: He sees CatNap as expendable—this is character development turned cold.

• Lore expansion: The “Hour of Joy” adds depth to the series’ dark past, implicating all monsters including CatNap in the mass killings.

In Summary
“Deep Sleep” marks a dark turn in the storyline: CatNap emerges as a tragic figure—once human, turned guardian, then weapon, until he meets a brutal end at the hands of the Puppet Master himself.

His sacrifice—willing or not—yields Poppy and the player deeper insight into the Prototype’s origins and paves the way for a tense descent into Chapter 4.
