In this episode Caroline is quite busy. She rescues several sims from drowning - I actually lost count but I think it was more than 6 all up throughout the video. She also finally managed to beat one shark in a fight. That completes her requirement for the next step in her quest to find Refuge Island, but I've decided to keep her there and try for the badge to beat 3 sharks in a fight. So next episode she'll be fighting two sharks at the very start.
Caroline did a few other things too - such as chat with Triton King and read a book at the library.
