My first shark sighting, and just a little too close for comfort (photo)

That happened to my sim too while she was trying to interact with her dolphin. It was going well when the dolphin suddenly squealed in terror, dove in the water and swam away. An enormous shark passed by very near to her. My sim then developed the tense 'finned fear' moodlet and immediately turned to swim for shore using a fast front crawl. I didn't even direct her to do that! It was very realistic in the reactions of both dolphin and sim!
