The Kine Society, lead by Sinjin Balani, is featured heavily in the handheld adaptation of The Sims 2 for PSP, but it also shows up briefly in the Nintendo DS version, under the guidance of everybody’s favourite goth girlfriend, Ava Cadavra. The members of this delightfully cooky group worship the great cow Beelzebeef, also know as the Prime Heifer — a force of great evil in the Sims universe. The Bovinomicon, the great cow’s religious book states that:

– The great cow Beelzebeef slumbers beneath the surface of the earth.
– When Beelzebeef rises again, she will awaken the Elder Herd.
– The Elder Herd will trample all those who stray from the teachings of the Kine.
– Once the earth is cleansed, there will be a new era of peace and delicious grass.
We can only assume what “once the earth is cleansed” implies, but it’s probably murder. Maybe.
Given that the Sims 2 handheld games share characters with the mainline PC titles, it’s safe to assume that they’re canon to the main story. So when you’re setting up your family for life in Strangetown, watch out — there might just be an ancient cow cult growing beneath your feet.
I also just came across this youtuber who played this chapter in the game. At the 25 min mark for the action. Take a look. It's absolutely WILD

I've played with this personally in TS2 DS. This is how he appears there:
