I can't get the bone to move to the lower right hand corner of the world randomly. I want to create a bone pile. I keep getting an error with the getRandomNumber method. Thank you in advance for your help.

Try this: 
if (isTouching(Bone.class))
{
    removeTouching(Bone.class);
    getWorld().addObject(new Bone2(), 894, 890+Greenfoot.getRandomNumber(6));
}

Perfect - I adjusted the X and Y axis locations, added a higher random number, added randomness to X axis, and achieved the final outcome of a pile of bones - thanks for all your help!
