Sidekicks would be awesome! Here are my ideas.
One of the seven dwarves, probably either Dopey or Grumpy.
Sebastian...or Flounder if they put in swimming mechanics.
Cogsworth and/or Lumiere.
Abu and/or Iago.
Meeko and/or Flit.
Djali.
Terk.
Mushu.
Bolt, unless he becomes a playable character (which I doubt) then Mittens or Rhino.
Ray.
Sour Bill...or Q-Bert if they can get the rights!
Pascal.
Olaf.
