Step 1: Make the Body
On the first picture, please differentiate: Up on the picture are 4 2-lego-unit long axle, and down on the picture are 6 pegs.
Step 2: Make the Hands
I purposely make bad palms to save weight.
On the first pictures, beside number 4 are 4 4-lego-unit long axles
Step 3: Make the Legs and Assembly
And after assembly, you can make it as a model, or play with it if you like so.
And that's all.
