Watermelons!

Here's code for endlessly generating watermelons, with the rind color changing depending on if the mouse is pressed.

void setup() {
  //canvas color
  background(255);
 
  //size of the canvas
  size(600, 600);
 
  noStroke();
  frameRate(24);
}

void draw() {
  if (mousePressed) {
    float x = random(100, 500);
    float y = random(0, 500);
    fill(153, 153, 255);
    arc(x, y, 200, 200, 0, PI, OPEN);
   
    fill(182,214,131);
    arc(x, y, 180, 180, 0, PI, OPEN);
   
    fill(211,54,45);
    arc(x, y, 175, 175, 0, PI, OPEN);
   
    fill(0);
    ellipse(x-40,y+50,8,8);
    ellipse(x,y+50,8,8);
    ellipse(x+40,y+50,8,8);
    ellipse(x-20,y+25,8,8);
    ellipse(x+20,y+25,8,8);
  } else {
    float x = random(100, 500);
    float y = random(0, 500);
    fill(81, 119, 26);
    arc(x, y, 200, 200, 0, PI, OPEN);
   
    fill(182,214,131);
    arc(x, y, 180, 180, 0, PI, OPEN);
   
    fill(211,54,45);
    arc(x, y, 175, 175, 0, PI, OPEN);
   
    fill(0);
    ellipse(x-40,y+50,8,8);
    ellipse(x,y+50,8,8);
    ellipse(x+40,y+50,8,8);
    ellipse(x-20,y+25,8,8);
    ellipse(x+20,y+25,8,8);
  }
