Animation trickery (Patreon)

(This is mainly nuts-and-bolts type of post that maybe 10 people will find interesting, everyone else can enjoy the boobs.)

So, the above clip seems pretty simple, right? But, how do you get the mouthpiece to move first with the hand, then with the head? The answer's actually pretty simple: You don't use one mouthpiece, you use two.

Have one mouthpiece attached to the glove, and one to the head. Then, animate the scene in two parts. First, with the mouthpiece in the glove visible:

Then animate the second part of the clip, with the mouthpiece in the head visible:

Then you splice the two together, and there you go!
