I've trapped a Blue I too. I've been figuring out the 0_game.dat file format, and needed to find out how the game keeps track of which item the Blue I has stolen.

Oddly, I couldn't get it to steal something from me. I walked right up to it and pushed it, and still nothing happened. So I've dug a pit, as you suggest, and just to be sure I made my pit 12 blocks deep. Here is a cross-section map:



There's a little overhang that prevents me from actually falling into the pit, but that also makes it hard to see my little Georgie. I can see it by looking down and jumping up at the same time.
