Null

Uh oh! A vent full of mysterious black goo (which may or may not be ichor) burst open, splashing Poppy with the black substance. To her chagrin, the goo is not only sticky, but it's also spreading. No matter how hard she tries, she cannot get the goo off, before it encases her entirely in the black goo, suppressing her cries before molding her into a blank, shapeless, null blob. After this, no traces of her remain.

After months of not posting a transformation/TF artwork, here's one! Null TFs are something I'm kind of fascinated by, so I might as well have a try at having a goo at one. The green color I chose on a whim, possibly because it contrasts with the girl the most.
