The final episode of the Speed Nguyen's Deep Dive Podcast consist primarily of YouTube video transcripts and related Reddit discussions focused on the fan-created "Nightmare Critters" and "Smiling Critters" from the Poppy Playtime horror franchise. Multiple transcripts from the INUbis YouTube channel showcase animated fan content, including songs like "SMILE EVERYDAY" and animated shorts like "HIDE AND SLEEP" and "SMILING IN THE RAIN," which explore the personalities and interactions of these characters, particularly DogDay and CatNap. A large Reddit thread expresses intense criticism of the official Nightmare Critters, arguing that they lack lore, serve no purpose in the game's story, and were likely introduced by the creators for merchandising and cash-grab opportunities, despite fans like INUbis creating compelling content for them. The additional Reddit source confirms that "Smiling in the Rain" is considered a sequel to other fan animations, highlighting the community's significant role in developing the characters' narrative outside of the official game.
