Dlabs will mate autonomously, but need doors and the will to spawn baby Dlabs. After 20 minutes, the baby Dlab will grow up to an adult.
Dlabs drop nothing when killed.
Upon spawning, Dlabs will leave their houses and start to explore the neighborhood. Generally, they wander aimlessly inside the neighborhood during the day. They can go indoors or outdoors. Occasionally, two Dlabs can stop and turn to look at each other, in a behavior called socializing, in which they will ogle at another Dlab for 4.5 seconds at a time. In the case of players, they will continuously gaze at them as long as the player is close, unless the Dlab attempts to get into a home at night, farm food, or flee from a cannibal. When a player attacks a Dlab, the Dlab will not flee, but their face sign will change to a "😞" expression if it is in a neighborhood.
Dlabs, like other creatures, will find trails around obstacles and will avoid harmful objects and walking off landmasses. However, in crowded situations, it is possible for one Dlab to shove another off of a ledge or into danger. At night or during storms, Dlabs will run inside, closing entrances, and staying indoors until morning. In the morning they will head outside and resume regular behavior.
Dlabs will flee from cannibals within 26 feet. If a Dlab finds itself outside the neighborhood boundary, or a Dlab without a neighborhood detects a neighborhood boundary within 105 feet, it will move back within the boundary fast. A Dlab taken more than 105 feet away from its neighborhood boundary will forget the neighborhood within 6 seconds. Whether in a neighborhood or not, a Dlab is never prone to despawning.
Dlabs cannot open trapdoors, fence gates, or steel doors.
There is evidence that Dlabs are prone to overfilling certain areas of a neighborhood while leaving other areas completely empty. When moving inside, the programming prefers ingresses within 52 feet. It also tends to prefer doors with few Dlabs nearby, however "nearby" in this case is only 5 feet and, when moving inside, Dlabs prefer to move 8 feet inside when the inside is to the south or east and therefore will be out of range of this check. During the day, it has been observed that Dlabs will cluster near a trapped Dlab or any existing sizable cluster of Dlabs, due to the "socialize" programming routine overriding their inclination to wander.
