But there are plenty of other ways you could draw them! This is just an arbitrary way to draw the legs that makes them longer (vertically) as you move the mouse.

It might be a very silly question but I was wondering why in this lines:

// Draw Zoog’s legs
stroke(0);
// The legs are drawn according to the mouse location and the previous mouse location.
line(mouseX-10,mouseY+50,pmouseX-10,pmouseY+60);
line(mouseX+10,mouseY+50,pmouseX+10,pmouseY+60);

pmouseX has the same numerical value as mouseX but pmouseY doesn’t?
