One of the plot points of the Girls Underground archetype is:

She interacts with people or things that are somehow connected to her ‘normal’ life at home, or briefly returns home in the middle of the journey.

While this is found in many GU stories, it is exemplified best, perhaps, by the original inspiration for the whole idea: Labyrinth. Not only does Sarah return to her own bedroom again while still on her quest (via the Junk Lady’s deception), but many of the creatures and things she encounters during her stay in the labyrinth (including the labyrinth itself) are echoes of items she has in her room: dolls, stuffed animals, posters, books, games, toys. This is illustrated wonderfully by this amazing set of animated gifs, juxtaposing the childhood object with its manifestation in the otherworld (courtesy of the awesome blog FuckYeahLabyrinth):
