Looking for an old dos game, please help!

[scramble]

I`m trying to find an old game that I played about eight years ago. It was an adventure/puzzle game, and the graphics and play type was very similar to Day of the tentackle (push, pull, talk, walk and so on). It all started with this guy with a green shirt and brown pants (you) hanging upside-down in a prison cell and you had to fool this orc-like guard to get out. Afterwards you walk to the left down a hall where all the walls are made of crystals/jewels, and then you fall down into this strange world and one of the things I can remember is this BIG red mouth that just stood there, and that you found this remote control. Does anyone have an idea of what game this is?
