Anybody know where to find a story about a girl and her friends who all gained weight after reading a magazine article about boosting their self esteem by ignoring their weight? I believe the main character worked at an ice cream stand during the summers.

By some chance does anyone have the text or a link to a couple of old Fantasy Feeder stories? I believe one was titled 'The Not So Little Mermaid' or something, and I can't remember the other title but I do know the main characters were named Misty and Caitlyn and they were on some island for some wealthy guy. Thanks for any help.
