A demo of “Rise of the Lord of Tentacles 2” was released on the Ero-Mania blog a while back (click here for more info). This demo contained an animated intro, featuring some scenes in a village that had been “taken over” by the Lord’s tentacle minions. This tentacle hentai gif below is from one of those scenes ^_^
This animation was also added to the “Animated Gifs” section.
