Following is a version of Example 6-11 (“multiple Zoogs”) that calls a function to draw Zoog. Write the function definition that completes this sketch. Feel free to redesign Zoog in the process. 

void setup() {
  size(400,200);  // Set the size of the window
  smooth();       // Enables Anti-Aliasing (smooth edges on shapes)
}

void draw() {
  background(255);  // Draw a white background 
  int y = height/2;
  // Multiple versions of Zoog are displayed by using a for loop
  for (int x = 80; x < width; x+= 80) {
    drawZoog(x,100,60,60,16);
  }
}
