Yakism is a newly formed religion for people who love Yaks.

People must show their love for the Yak by praying to the Almighty Yak daily and asking for him to bless you with his Yakness! It is believed that sleeping with the Yaks will help rid you of certain illness’s, so many followers wear a lock of Yaks hair around their necks to protect them through out their lives. Also followers of Yakism are sworn enemies of the RACOONS!!
