She made a second appearance in The Sims: Superstar as the titular character in a 1960s movie.
"In this classic pulp movie from the Sixties, the friendly Betty Yeti is turned into a rampaging monster when she comes in contact with radioactive waste from a SimCity military waste facility. The radioactivity causes her to grow to enormous size and sends her on a berserk rampage. In this particular poster, she is pictured climbing one of many SimCity windmills. During the conclusion of the film, scientists find a way of reversing the mutation and thus restore her to her usual affable self."
