This is Bull of Frost (Chys Khan), which is Yakutian colleague of Russian Grandpa Frost (Ded Moroz) and Santa Claus.
Bull of Frost dwells in Tomtor, Oymiakon ulus, which is the coldest place in Siberia. Winter lasts for 9 months in Tomtor, where the lowest temperature registered in Tomtor is -71,2 degrees Celsius. Due to the climate, there are no bulls or cows there. Scholars confirm that Bull of Frost is actually Mammoth, which is important personage in shamanictraditions.Chys Khan (Like Ded Moroz) also travels with a snow maiden. He also got to "chill" with Jamaican reggae singer Lenky Roy on his "I'VE NEVER BEEN SO COLD IN MY LIFE" tour to promote his album "Siberia".
