So this thought came up durring some trivia on the Boards. Did the Wampa in ESB remove the lightsaber from Luke's belt? I ask this cuz it's placed so perfectly in the snow, it just doesn't look like it could of fell there.
Then you have to ask the question why would a wampa do that anyway?
Seeing how the wampa is smart enough to freeze Lukes feet to a ceiling and hang him like meat in a meatlocker it's possible it knew the weapon was a threat. Or maybe wampa's simply like shiny cylinder objects?
