The I.C.E.R.C. (Dolphin and Whale) are among my favorite G-shocks. In fact, it was one of these that first got me interested in G-shocks. The whale backlight was the first time I had seen a watch with a custom backlight.
I only have four, but in time I hope to expand the collection. I just got the white Frog thanks to a trade made on WUS. I'm not really into the clear G-shocks as much, which account for many of the I.C.E.R.C. editions, so I have been focusing on the white and the darker colors.
My "grail" would be a blue jelly Frogman, which I know is hard to find and expensive. I know some of you on the forum have them, so let's see.... Post pics of yours. White, clear, blue jelly, red jelly, gray, black and yellow... Pink Riseman and Green Frogman welcome too! (Love the Sea and the Earth series)
