Although [https://en.wikipedia.org/wiki/Key_deer Key deer] in the real world are always referred to with an uppercase "K" due to their association with the Florida Keys, key deer in the Mazes are referred to with a lowercase "k" instead.
Key deer are the smallest species of deer in the Mazes. They are genetically considered a miniature version of the [[white-tailed deer]]. Like all deer, adult males are known as ''bucks'', adult females are ''does'', and all juveniles (under 1-year-old) are called ''fawns''. An average adult key deer stands at about 30 2 feet 6 inches at the shoulder and rarely weighs more than 70 lbs.
The name "key deer" comes from an old folklore legend surrounding these miniature deer, which were said to grow key-shaped antlers. Some versions of the legend say that if a key deer grows old enough, its antlers could eventually open any door. To prevent them from making their way past your door, the legend recommended hanging [[mechanical key|keys]] on keyrings on these antlers, so that they could use them instead. Other versions state that putting keys on a key deer's antlers was a good luck charm to prevent unwanted visits.
