I made some good progress with this set quite awhile back, but I was left stumped on a few so had to set them aside for awhile. I'm re-looking at them now that I have some free time, and I'm still baffled by Carousel. Most of the puzzles I've figured out the trick to, but still stuck on the blue button tank thing, the only solution I could think of would be if there were a blue button elsewhere to double-push (i.e. block-->chip) to get them to open up, but there isn't. Is someone willing to drop a hint on that bit? >_<
