Her name is likely a pun on "kinda [kind of] pleasant", especially since her husband's name is Les (or "less pleasant"). According to her SimDNA in SimPE, Kynda's hair was black before it turned grey. According to her age data, she had 36 days left in the elderlife stage when she died. Like most pre-made deceased Sims from The Sims 2, Kynda is completely unplayable without the use of hacks or third party programs, such as SimPE. She, like Irma Oldie, has an unused hairstyle, two buns on each side of her head with a braid. That style was probably intended to be used in The Sims 2, but there is a similar hair style that is close to it.
This Sim has no character data and cannot be resurrected in-game. For more information, read this guide.
