Lucy planned to participate in the Great Neopia Bake-Off, but realised she was out of flour. She eventually found a shop owned by a mutant Lenny, and got some flour from within. She used it bake a batch of cookies at the Bake-Off, and gave everyone a sample. It wasn't until she got home that she realised she had actually purchased Flour Brand Zombie Powder. She left her house to tell the authorities, while beginning to show signs of becoming a zombie.
From the picture with the story, it appears Lucy is a blue Usul. She appeared in issue #19.
