In the extra downloadable content level, instead of exploring dreamlike locations, the player is taken to another house with the objective of finding and thawing five frozen dolls by playing music or turning on the TV.

The party is then interrupted by a visitor at the front door who is hidden from the player, but the story suggests it is the toddler's father, who has divorced the mother.

The conversation is muffled and partly kept from the toddler as the mother raises her voice, refusing the father's request to see his child.

The gift is revealed to be a sentient teddy bear, who climbs out of the box and hides in the chest until the player finds him.

After a few minutes of playing together with a music box, a stuffed pink elephant, a storybook, and a toy train, they go into the closet, which turns out to be a large, dark room filled with long, dark-colored coats.

The small adventure is ended by the mother finding them; she tells the toddler, gently but ominously, to stop hiding from her and puts them to bed.

The search leads them to discover a slide that takes them to a small playhouse within the void, and the door found inside leads them into a journey through several surreal environments, consisting of an underground playground, a dilapidated mansion that has merged with a marshy forest, and a bizarre series of corridors created by hundreds of closets.

The memories take the form of four objects: The mother's pendant from her necklace shown at the start of the game, the music box she plays to put the toddler to sleep at night, the storybook, and the pink elephant.

Throughout the search, the player is pursued by a large, feminine, troll-like monster and a creature with glowing white eyes, who has a coat as a body like the ones in the toddler's closet earlier.

The toddler heads downstairs to find their mother crying in the kitchen, with the damaged Teddy in one hand, and an empty wine bottle in the other, which she drops.

An expansion level available through downloadable content is set before the events of the main story, again told from the toddler's point of view.

The toddler is wandering through a winter environment and finds five dolls surrounding a light that breaks, sending the player to a house different from the one shown in the main story.

They see Teddy turning a wheel, where the crib is being held, revealing a room with lifeless dolls, all memory items, and a giant cooking pot.

From that moment, his neck cracks and giant skeleton-like hands come out of his body, revealing his true ghostly form "The Nightmare".
