Okay so apparently the choppy animations of view 2 of the familiar while she has big breasts only happened while she's wearing that black lingerie, the animation was fine when she's naked (which is when she's pregnant cuz she only took the lingerie off).
I think these choppy pits are pieces of the lingerie that poked out (cuz the familiar's breasts got bigger), but Tink forgot to colour them black to match the lingerie.
