I've been having a bit of fun using slices of cucumber as fish scales. Here are a couple of fun meals I've made for SchmoopBoy over the past few weeks.
Mermaid (or is it Medusa with that hair? ;)
The mermaid's head and body is a freehand cutout from a slice of toast. Carrots make her top, as well as her hair. For the face there are raisin eyes, a red bell pepper mouth, and a small toast triangle nose. The tail, of course, is sliced cucumber.
The fish body is a large slice off an apple, almost a half. The fins and tail are each thirds of a cheese quesadilla. A carrot slice is the eye, and a grape tomato cut in half forms the mouth. I only made cucumber scales for the tail this time.
