if someone is put into a sprite, when they go through walls, it leaves that slime. The slime has properties of their aspect. (Nannasprite making healing slime, because life, and john using it to make healing gushers)

Oh, that IS true! I forgot entirely about the ecto-goo Sprites leave.

… Which actually raises other questions like. Can Sprites actually go through people as well? And, are they like. Slimy to the touch?

… I had never quite considered this about Sprites and I am suddenly fascinated.
