I can imagine quite a good plot behind this. Like the junkyard could symbolize destructive or bad behavior for the child and so he refuses to leave due to lacking a good parent or guardian. If he tries to leave he'll pretty much struggle doing it while going through the junkyard to find an exit. This animation was quite thought provoking.
The sound design is great
Sorta bare, but very creepy.
