Your friend continues to stare at your growing sea green fish tail while your legs slowly disappear, and seems too shocked to give any reply. Then she suddenly comes to her senses and decides to run, but she can't even get up. When she turns around to look why her legs aren't responding, she sees that her entire lower half is a smooth grey tail, ending in large tail fins of the same structure. She can't believe it and thinks she must be hallucinating, but after touching it with her hand and feeling a response from her new flesh she concludes it is indeed real but apparently didn't notice the changes while watching you change. She looks back at you, your lower half now being a green fish tail, while hers looks like a dolphin tail. She flaps her tail up and down angrily. "Why is this happening to us?" You think..."well, the most logical explanation would be that we've seen them and can't leave because we're not supposed to know about their existence." She exclaims:"But I don't wanna be a fish! Let's go over to those mermaids and tell them to change us back!" as she starts flopping towards the water on her hands and tail.
