Sinjin Balani is the cousin of Lazlo Curious . He runs the Kine Dairy in The Sims 2 for PlayStation Portable. He is the "herd leader" of the Kine Society. Sinjin leads the player through a number of tests before promoting him/her to a yearling. In the cut-scene, Doctor Dominic Newlow will take the famous Beelzebeef, a huge cow, and Sinjin will not be pleased with the results. He discovers the Kine Society was founded upon a lie, but decides not to break it to the other members, saying they have found peace with this lifestyle.
He does not appear in the PC version and it is unknown what side of the family he is from. It is only revealed that he is Lazlo's cousin. However, no relation between the Curious brothers was revealed in this version.
