Adding more joints & controllers to the character tool rigs

Hey all,

More specific to the title, I’m looking to add a tongue to the quadruped rig via the character tool. Is there a best practice for this?

I’ve included a screenshot of what the object tab looks like. Here’s some context:
• The character tool is skinned to the Cat mesh
• The tongue joints are parent constrained to their respected controllers and is bound to the cat_tongue mesh

Now, my thought process (to no avail) was to parent constrain the tongue_con_base to the jaw controller but that pops the tongue out of place. All of the coords are frozen and zeroed out. Appreciate any thoughts. Happy to provide anymore information that’s needed.
