One of the flat-topped pegs anchoring the fuzzy black upholstery / carpet to the back of the rear seats went walkabout a while ago, but the situation only became critical after I vacuumed the crud out of the car.
Living in the future simplifies things:
Rather than getting all fancy with barbed ends and suchlike, I just slathered the stem with hot-melt glue, jammed it in place, and waited a few breaths:
The vivid yellow stuff is seat cushion foam.
3D printing is wonderful for simple parts like that.
The OpenSCAD source code is simple enough:

HeadThick = 1.5;
HeadOD = 25.0;
PegLength = 10.0;
PegOD = 8.0;
SlotWidth = 1.5;
rotate_extrude(angle=360,$fn=32)
polygon(points=[[0,0],[HeadOD/2 - 1,0],[HeadOD/2,HeadThick],[0,HeadThick]]);
difference() {
rotate(180/8)
cylinder(d=PegOD,h=10.0,$fn=8);
translate([0,0,HeadThick ])
cylinder(d=PegOD/2,h=PegLength,$fn=8);
for (a=[0,90])
rotate(a)
translate([0,0,PegLength/2 + HeadThick + 1.0])
cube([SlotWidth,10.0,PegLength],center=true);
}

I’m currently doing battle with mice in our Foresters. AFAIK, there’s one or more mouse-sized passages in the rear spare-tire/gubbage tray area, and once in, they can go everywhere. Debris in the back seat is bad enough; mice in the heater ducts are worse. Nests in the spare tire, right out.
Had some mild success with one of those vent-clip air fresheners in the back tray (and the occasional glue trap*), but the current rodents don’t seem to mind the smell. Sigh.
Starting to think of urethane foam sealant, though it that doesn’t work, I’ll have an even worse mess on my hands.
((*)) Protip: if used, check early and often. Don’t ask how I know. [wince]
Still doing battle; freshener brand #2 had a different activation method than #1, and I missed it. Hope the smell works.
These are deer mice, known carriers for Hantavirus. Bad news.
