Frankenstein
In The Sims: Livin' Large, a Sim can temporarily turn into a Frankenstein-like monster. During this time the Sim is uncontrollable. The Sim can become the monster by drinking a purple potion from the Concoctinator Chemistry Set.
While turned, he walks around using items randomly, which will always break them. However, art easels will keep him busy. He will paint child-like paintings on them. He can be contained by surrounding him with art easels, which he will always use. Once he turns back to normal, repair what he has broken and sell his paintings (which sell for a lot).
