KJH is a family-friendly, mobile carnival, organised to promote the products, brands and stations under Media Prima Television Networks. Since its debut in 2003, KJH has been a yearly event that gathers carnival-goers of all ages, followers of the local entertainment scene and celebrities for a full day of fun activities and entertainment. The highlight of the carnival is the Konsert KJH that features a line-up of popular local music acts. The concert is also aired live on TV3.

KJH is usually held for 3 days and 2 nights. Local companies and businesses are welcomed to sell and promote their products at this carnival too.
