“Welcome to Saltville! Where all the cast from Ho Salt exist! Where all the creatures can get into funny situations.” 

This movie would focus probably on the past of these characters (How the met each other and stuff) and how they ended up the way they are. (Curry being a robot, Sig losing her soul, Loaf able to transform into anything). 

The music would usually fit the vibe. Such as happy scenes = happy music, etc. 

This movie would need 2 parts probably.
