Jeremy had his nickname "Da Hedgehog" bestowed upon him by dwarf Bihl Nargold after an incident on the World's Edge Mountains in 2498. Jeremy had been teleported in from Middenheim to trade with the Dwarfs, and had dressed in a T-shirt and shorts, expecting warm weather and thinking he was going to the desert. But the weather in the mountains was blizzard conditions, which chilled him to the point of hypothermia. Upon arriving at back home, Jeremy was immediately whisked away to warm up in a hot bath. When he had finished, his skin had taken on a pink hue from the temperature extremes, and the hairs on his body were standing on end. Nargold's comment upon seeing Jeremy after the shower was, "You are a hedgehog, my friend. A walking, talking hedgehog". Contrary to popular belief, the nickname had nothing to do with Jeremy's (subsequent) weight gain, as he was quite physically fit at the time.
