So I was messing around with my Trypticon prototype and came across his tower/canon. Just for fun I decieded to put a battery in and make a sure it still lite up. So I'm looking at it and all of a sudden it start blinking. At first I just thought I had a low battery, so I went and got a fresh one. It did the samething. So for a sanity check I dug out my other proto and it did the samething. So just to make sure I wasn't completely insane I dug out my Trypticon from when I was a child, put a battery in, and the light stayed on continiousely. So I took a video of it. The prototype is the one on the left (pinky purple color), and the regular(purple) release is on the right. http://www.youtube.com/watch?v=4dsVGi2cllY There are a number of differences between the proto Trypticon and the release version. There are a few molding changes on the green parts on the arm/legs, and all the purple parts are different, and one of the ones I have has the unreleased stickers that are seen in the catalog. If I ever get around to it, I'll do a review of the two protos ver. the release.
