Geography
In this map, both the S.S. Dolphin and the Onions are inaccessible to Olimar, as they are both either out of the map entirely or too high for him to reach. The area starts out in the middle of a large path, one way having an arch, and the other leading to a large circular, albeit barren arena-like plain. The textures are mostly for testing, nothing much special in particular about them. There are a handful of arches as the path continues, leading to another arena-like area, but instead filled with holes that lead very far down and once Olimar falls down, it's impossible to get back up. There's is then a half complete bridge pointed towards a circle. The map is very linear and rather small, and is very similar to other test maps.
