complete noob question on forloops

hi everybody iv just started to learn processing and we have a project which is to call a function with a for loop
iv been trying for the the last couple of hours but no joy. for this assignment we have to call multipliable versions of zoog with a for loop. i have been looking for examples but almost all of them are used to repeat shapes and not creations like zoog. could anyone point me to some good examples or steer me to a good tutorial on this point

// Example 7-5: Zoog with functions

float x = 300;

float y = 300;

float w = 60;

float h = 60;

float eyeSize = 16;

void setup() {

  size(600,600);

  smooth();

}

void draw() {

  background(255); // Draw a black background



  // mouseX position determines speed factor for moveZoog function

  float factor = constrain(mouseX/10,0,5);

  // The code for changing the variables associated with Zoog and displaying Zoog is moved outside of draw() and into functions called here.

  // The functions are given arguments, such as â€œJiggle Zoog by the following factorâ€� and â€œdraw Zoog with the following eye color.

  jiggleZoog(factor);

  // pass in a color to drawZoog

  // function for eye's color

  float d = dist(x,y,mouseX,mouseY);

  color c = color(d);

  drawZoog(c);

}

void jiggleZoog(float speed) {

  // Change the x and y location of Zoog randomly

  x = x + random( - 1,1)*speed;

  y = y + random( - 1,1)*speed;

  // Constrain Zoog to window

  x = constrain(x,0,width);

  y = constrain(y,0,height);

}

void drawZoog(color eyeColor) {

  // Set ellipses and rects to CENTER mode

  ellipseMode(CENTER);

  rectMode(CENTER);

  // Draw Zoog's arms with a for loop



  for (float i = y - h/3; i < y + h/2; i += 10) {

   stroke(0);

   line(x - w/4,i,x + w/4,i);

   stroke(0);

  fill(175);

  rect(x,y,w/6,h);

  // Draw Zoog's head

  stroke(0);

  fill(255);

  ellipse(x,y - h,w,h);

  // Draw Zoog's eyes

  fill(eyeColor);

  ellipse(x - w/3,y - h,eyeSize,eyeSize*2);

  ellipse(x + w/3,y - h,eyeSize,eyeSize*2);

  // Draw Zoog's legs

  stroke(0);

  line(x - w/12,y + h/2,x - w/4,y + h/2 + 10);

  line(x + w/12,y + h/2,x + w/4,y + h/2 + 10);

}

  // Draw Zoog's body

}
