If you're using proper tools everything that you're going to animate needs to be on the same layer.
After the puppet pin animation is complete pre-compose the layer then adjust the position and add any additional animation.
Please type puppet pin in the search help field at the top right corner of AE and go through the training materials you will find there.
Thanks. I can use puppet pins to animate a single layer character, so there's nothing new in the training resources.
I'm trying to animate a gait using multiple layers for limbs. Perhaps my mistake was trying to make the character have a outline like a paper cut-out. Too ambitious.
Can you not make two arm layers, one with the outline and one without. Put the body layer between the two.
