Take out the blow torch. First, aim it to where you want it to go (because once you do it, you cant aim it). Press X+A+B all at the same time. The weapon selection bar should appear, but wait until your worm is done blowtorching to select your next weapon. If you don't wait until your worm finishes blowtorching the game will freeze.
I found some awesome levels and I wrote the level codes down. The best place for these levels is London. I find them easier to write down if you write down 3 digits at a time. Here they are... 804527289, 006893241, 038961246, 009096726, (This one's best at snowman land -> 038961241) And you should be able to remember these next 2 pretty much on your own. They are 000000001 and 000000002.
