i cant get the back pistons to come out
Yes you can. Trust me. Took me hours to get done, getting up the courage to try it like IllJedi said, but HE WAS RIGHT!
Hold each yellow piston shell gripped tightly, thumb toward the silver/black tip, and using the thumb, push (you can use the other hand too) evenly until that first, scary, pop! Then again! And again, until it inches out. Once you see this thin line in the middle of the silver, you are out as far as it will go.
Then, push it back in and out some, you certainly know how to push a piston in and out of a hole by now!
That will loosen it up enough so you can feel confident to attach the piston black bases to those ball joint holders on the back of the body harness segment.
They just snap onto those.
I snapped mine on while the silver part was fully extended. Once you do, you can move the arm up and down, and it will slightly snap at each catch and hold the pose each segment. It is really ingenious!
Just be patient! I was scared too!
YOU CAN DO IT!
But, you are P!TU, so try not to break anything or stab yourself.
Let us know if this helps!
Rory, yes. She is removable, as well as easy to disassemble.
Good luck King!
