G25 contains blank snow and a corner of the aquarium. H26 contains blank snow. I27 contains building 242, described as follows: Even with the signs long gone, the large garage doors and the design of the building make it clear this is a firehouse. There's even two poles that can be used to slide all the way from the third floor down to the first. There aren't any fire trucks in the garage, sadly, but there are a few simple beds for sleeping in, and two bathrooms with working public showers. The water is cold, though.
