The mermaid looked around for a bit and pointed straight at me! "I know you did this! Well I know magic too!"
She pointed her finger at me and I was hit by a wave of energy. Then I felt wet and clammy, and felt wet paving underfoot. Looking down, I saw that my feet had turned to huge green flippers, breaking apart my shoes. My pants were half mast due to my longer legs and my hnds were also webbed. Feeling my face, I found that my hair, ears and nose had vanished.
The mermaid had turned me into a frog!
"Don't bother trying to turn back." she said "My water magic is more powerful than that ring. Now carry me to some water, and I think you'd better do something about the other people around."
After wishing that everyone else would forget they saw a mermaid and an anthro-frog, and that our forms would be invisible to everyone else, I picked up the mermaid and left.
