When the Smiling Critters, an in-universe toy line heavily featured in Chapter 3, was first revealed on Mob Entertainment's Twitter account, the image posted featured the full line-up of characters. However, an hour after posting this, a second version of the line-up was posted, this one removing the character CatNap. The reason for this would be revealed in a video titled "CatNap Recall", which was first discovered through an elaborate ARG held by the developers to tease Chapter 3, and also serves as the intro for Chapter 3. The video depicts a news report centered around the Smiling Critters, which reveals that CatNap was removed from the toy line after parents began to report that their children had experienced violent nightmares after inhaling the scent the toy emitted.
