Properly Inspired

Been all over the place. Blown all kinds of things up. I thought I might have some trouble carrying on the trend, what with the water and all, but it's all just a matter of inspiration. I found something volatile enough to make bombs out of! There's a bunch of kelp hanging under the terrace to the southwest. Normally kelp stores gas that makes it float - this kelp produces a different kind of heavy gas. It keeps it hanging, but also makes for great explosions. Gather me some?
