directory to access the hidden content. Blizzard later included a well known cheat code in 1998's StarCraft which specifically denies the existence of a cow level. Blizzard employees were reportedly amused by the hoax, which led to the creation of the cow level in Diablo II as postgame content. To access the level, also known as the "Moo Moo Farm", players must collect two specific magical items and complete the game by slaying its final boss, then travel to the hub area of the game's first act when playing at a difficulty level they have already completed. Combining the aforementioned items using a device known as the Horadric Cube in the area will create a red portal nearby, which grants access to an area populated by a large host of Hell Bovines, hostile bipedal cattle armed with polearms. The Hell Bovines are led by a boss enemy known as "The Cow King": defeating it will confer special items as quest reward but disables the red portal, which prevents the player from revisiting the area again within that difficulty mode. In retrospect, Diablo III lead designer Jay Wilson liked that the content of Diablo II cow level came up with a purpose, but felt that it nearly replaced or overshadowed part of the game. He said that its sequel would handle the concept of a secret level with better care. Blizzard introduced levels with similar themes to the cow level in certain titles released after Diablo II, with Diablo III featuring multiple such levels that often require players to complete a complicated procedure of actions to access. "Whimsyshire", also known as the "Pony Level", does not feature bovine enemies, but continues the surrealistic theme of the original cow level and includes a cameo appearance by the ghost of the Cow King. "Not the Cow Level" was a temporary level released exclusively for PC platforms in May 2015 to celebrate the third anniversary of Diablo III, and featured an enemy boss known as the Cow Queen which could be encountered after players slay an enemy unit called Herald of the Queen. In March 2016, Blizzard released a bonus level which paid homage to Diablo III artist and environmental designer Kevin Kanai Griffith, who died in late 2014. In "Kanai’s Stomping Grounds", players would battle bovine enemies alongside Chief Elder Kanai, modelled after Griffith's Barbarian player character. As part of the 20th anniversary
