Knut Futa is one of the pre-created, yet unplayable Sims featured in The Sims 2. When he was alive, he resided in Strangetown, and worked as a deliveryman. One house he delivered to was that of Olive Specter. He is not buried on her lot, but according to her memories he may have been one of her victims.
Although he looks like an adult, he doesn't actually have an age. Because he has no age, the game thinks he is a baby and he acts like one. This can be fixed with SimPE or the Sim Modder.[TS2:NL] He also does not have an aspiration or sign.[1]
Also despite Olive's memory of his death the game does not recognize him as deceased. He has Power aspiration.
It is unknown if he is related to Alvin Futa of Pleasantview; this is left up to the imaginations of individual players.
Trivia
He can be fixed easily with SimPE by giving him the proper data, e.g. age, aspiration, sign and personality points, yet there is no guarantee this won't corrupt the game.
