Making Single Unit Body Character Walk

[b.diskin]

I am having trouble making my single-unit body character walk. The character is a sheet of paper with arms and legs.  (See attached.) When I use the arrow keys to make it walk it warps horribly.

I narrowed it down to a flaw with the design, it's hierarchy, how I rigged it or how I've tagged it. :0 )

I used both Footy and Eliza puppets for reference with hierarchy and tagging.  (See attached) Does anyone have ideas what the problem is and how to correct it?

I've uploaded the puppet to Adobe Cloud for you to examine.

There are many causes.
Please share your puppets if possible.
I can't seem to attach it here.
It is preferable to share it via Google Drive or Dropbox.
Please be careful to set the permissions.
