this one require prying off the arm.
The main concept is that I'd take the arm off and take some twine or string and loop it around the joint of the arm and then around the torso of the teddy trooper so it like something he pulls around with him. the eyes would be looking in that direction so that when you put the arm over there he's looking at it.
Because the real one would be three dimensional, none of the green outlines would exist, but some of the details, like the tips of the hands and feet and the zigzags on the chest I'd still do.
I might not do the colors like that with an actual one, and I'd probably add a little bit of detail on the helmet, the main thing I wanted to show was the arm idea.
