I like watching longplays of old adventure games (because they're usually more fun than havign to figure out the game's convoluted logic on your own), and I saw a few TFs in this video:
There's an ant disguised as Elvira at 1:23, a snake disguised as her at 2:50:50, and a succubus at 3:14:30. There's also a pair of female zombies at 3:17. I wouldn't suggest watching much else of the video, the game seems to be 80% comprised of the one thing I will not ever tolerate in a video game: mazes.
