Gather some brown and green clay.
First make a shell shape with the brown clay.
Make a ball of green clay and roll it on one side to make this rounded cone shape.
Bend up one side.
Next roll out some green and chop into 4 even sections
Form 4 even cylinders
Get another tiny ball of green clay
Roll it into a cylinder
Roll out one end even more
Cut off the excess
Oh cute a tail!
Now you should have all this.
Put the 4 cylinders into a square formation.
Put the brown on top
Now add the head...
Take a tiny bit of black
Make too teeny tiny little black balls
Poke holes in the head and stick the black in them to make eyes.
Use a blunt tool to make whatever pattern you desire on the shell. Mines sloppy but you get the idea.
Ad voila, there's you turtle!
From the other side too :)
