A Stock Aesop found mainly on children's shows, and also a plot. A character or characters have a messy room and learn a lesson when they find out how much easier things are for them once they have a tidy room. I searched and the closest thing I found to this was Trash of the Titans, but that just seems to describe someone whose room is in a constantly messy state or even vile - there's no aesop learned there. Compare/contrast It Came from the Fridge, which has a similar lesson, aimed at adults, about cleaning the icebox, not because it's easier to find stuff, but because rotten food is bad for your health (and is out to get you).
