        GreenfootImage img = new GreenfootImage(90,195);
        img.drawRect(0,0,89,199);
        setImage(img);
        counter = 0;     
    }

    public void updateImage()
    {
        GreenfootImage img = getImage();
        img.clear();
        img.setColor(Color.BLACK);        
        img.drawRect(0,0,89,194);
        img.setColor(Color.BLUE);
        img.fillRect(1,195-counter,88,counter);
    }

    public void act() 
    {
        Actor drop = getOneIntersectingObject(Drop.class);
        if(drop!=null){
            counter++;
            getWorld().removeObject(drop);
            updateImage();
        }
    }
}
Is there a way to make it so that my container is just a simple line and have blue stack buy 1 pixel height on top of the line as a my drop touches that line?

You could do something like this that I believe achieves what you want: 
public void act()
{
    Actor drop = getOneIntersectingObject(Drop.class);
    if (drop != null)
    {
        // Check if bottom of the drop reaches “top of container’s contents”
        if (drop.getY() + drop.getImage().getHeight() / 2 > getY() + getImage().getHeight() / 2 - counter)
        {
            counter++;
            getWorld().removeObject(drop);
            updateImage();
        }
    }
}
