1. I've already animated the dude who does stuff in this cartoon, but I didn't add his mouth bones. Is it too late to do that with the cartoon almost finished? And if not, how do I go about installing mouth bones? (Because Papagayo isn't working)

2. I want to put a new character into the cartoon at around frame 174, animate it doing one simple move, then taking it out of the cartoon entirely at frame 390 (cartoon length is 450 frames). How do I do this?
3. I forgot to add color to my character before putting in his bones and animating him! Is it possible to add color back in but still have the colored portions continue to move while his bones do? How?
Help!!!!!!
PS, I will post this cartoon when it's done. It's kinda cheesy old school and stupid, but I would like you to see what you helped me with. Thanks for all answers!!
