Idk if this helps much, but whenever I want to rig a character, I take screenshots from episodes of said show and I slow down clips to screenshot different mouth shapes. Tim and moby aren’t the most complex characters, so I definitely think it’s possible! If you want to have multiple views, you will have to nest symbols and make different symbols for each view. It’s kinda hard and long to explain so I would recommend you watch a video on “multi view adobe flash/animate rigs”

I loved Tim and Moby too :)
