How to open mouths in BrawlBox? (Link, C. Falcon, etc)

[Chaos_Knight]

Some characters like Link, Captain Falcon, and Ganondorf dont use face polygons for expressions and use an animated face. How I know how to move eyes in BB, but how do you open mouths?

C. Falcon has bones in his face for that stuff, just like donkey and diddy kong.
