I somehow flipped over one of the bars and bashed my head on the deck (wooden on ours rather than metal) when I was around 6 or 7 years old. No stitches, though I don’t see any noticeable scar. I don’t remember much aside from seeing blood and a headache.
I’m torn between “no teeth (just gums) and a mouth stuffed with chocolate pudding (specifically the one that many American buffet restaurants use)” and “crunching jagged jawbreakers (or rocks)”
