Husk

Husks are Hostile Mobs that were added in Update 0.15.0. They are variants of Zombies that spawn exclusively in Deserts.

Behavior
Husks are a stronger type of Zombies. Husks appear to be Zombies with yellow skin and ragged clothing. They do not burn in sunlight, unlike regular Zombies, and apply the Hunger Status Effect to any Player they land a successful attack on.
