"IceBeak has a fear of sharks. Nothing like them exist where she comes from (with the exception of the creature we know as the Greenland shark). She's heard countless stories about sharks and she became very fearful of them.
Sea Lilly, on the other hand, loves sharks. They are one of her favorite creatures in the sea, and finds them very misunderstood. Having lived underwater for many years, she's learned a few tricks on how to handle and approach them. She's here to show Icy that sharks aren't that scary, and how to best handle them. Heck, Icy should be relieved that the biggest sharks are harmless filter feeders like whales!"
