A दैत्य who was transformed into an animal. There is a story in the स्कन्द पुराण about him thus-Pulaka performed penance and got from शिव a boon that he should possess astonishing smell in his body. The demon used to entice even celestial ladies by means of his smell. He thus became a menace to the three worlds. देवस् complained to शिव . शिव got angry and commanded him to abandon his demoniac form and become an animal. Pulaka agreed to do so but requested शिव to grant him the smell even in his state of an animal. शिव granted that.
