Speaking of techniques-- I remember that Disney's Snow White being a kind of pastiche of different art styles and physics. The Fleischer Snow White, too, with the rotoscoping of Cab Calloway vs. all the bouncy, stretchy characters (all of which IIRC was done by a single animator). All based on practical constraints, I'm sure, but audiences enjoyed it and it's a valid and striking style. Does anyone still mix clashing styles/physics this way in modern animation? My superficial impression is that if a modern character has a gag where, say, its foot elongates to kick an opponent, it has to be part of a foot-elongating species of animal inside, complete with a 10-page backstory, who lives in a fully worked out Elongation Universe that has its own gaming physics engine and subreddit.
