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. However he can not be interacted with, and the game will force an error on a Sim, if they try and interact with him. This can be fixed with SimPE or the Sim Modder. He also does not have an aspiration. When editing in SimPE, Knut's zodiac sign is not recognized. He has the same facial structure as Johnson Pai. When attempting to open up Knut's DNA page, it will either appear blank, or it won't open at all. This happens with most of Olive's victims.
