The sheep, q, is a domestic quadrupedal animal first introduced in SLASH'EM and ported to dNetHack. Sheep are compatible steeds for riding and can have a saddle applied to them.
Sheep are always generated peaceful, and are often found in Sokoban. Lambs can also grow up into sheep at experience level 3.
A lamb is a baby sheep.
Dire sheep are somewhat more physically threatening than other types of sheep, and far more hostile. Each sheep has a 1/20 chance of dropping a woolen piece of cloth when killed.
Sheep are generally trivial to tame, but their attacks and base level are usually too weak to be worth it. Additionally, they are herbivorous and somewhat more difficult to keep fed than most pets.
