The hedgehog's back contains two large muscles that control the position of the quills. The average hedgehog has about 5,000 to 6,500 quills that are strong on the outer surface but filled with air pockets on the inside. When the creature is rolled into a ball, the quills on the back protect the tucked head, feet, and belly, which are not quilled.
Baby quills are especially sharp. Once she has her adult quills in, they will gradually get a little blunted at the ends over time - but that doesn't mean they'll stop being pokey. When a hedgehog's quills are down and relaxed, it feels kind of like running your hand through dry rice.
