The Echidna Tale/The Slime
From Create Your Own Story
Drawing inspiration from the monstrous oozes in tabletop and video games, and mixing it up with the offbeat goo girl fetish, you think of a wonderful design for a new child of yours. A girl made of jelly--beautiful but deathly acidic. Such a disarming creature would be excellent at claiming victims, like all of your greatest children could. You decide to call her the slime.
Of course, you'd have to find a girl to complete your vision.
