If the turtle is not carrying the heavy shell unfortunately density keeps the hard heavy shell at bottom and weaker belly with stumpy legs up.

More about gravity:

• With the rotation speed of the Earth (in ball terms) being much faster at the equator than further north or south, surely this affects the magical force of gravity?
  So, if I'm standing on the equator at the widest point of the alleged globe, spinning at 1000 mph, my weight will be 175lbs, if I then fly to either north or South poles (not actually allowed but lets wave that for now) at the narrowest point of the alleged Globe,the rotation of the earth would be reduced to around 150 mph, The gravitational pull if existent would have to be so great that my weight would be around 7000lbs and I would be squashed like a bug.
• The Solar System is travelling at an average speed of 828,000 km/h or 514,000 mph within its trajectory around the galactic centre but this somehow has no affect on the magical force of gravity either.
• The Moon does not fall into the Earth.
• The Earth does not fall into the Sun.
• Satellites do not fall into the Earth.
• Gravity is so strong that upside-down water at the surface of the ocean (near air) is being pulled to the centre of the earth but this force is also not that strong, in that this water can move in any direction with currents and tides, and be easily scooped, splashed, and thrown by a human hand.
• Why is gravity so strong to hold people, buildings and the oceans stuck to a spinning ball-Earth, but weak enough to allow balloons, birds, bugs, flowers, and smoke to easily rise against its awesome force?
