The first time the location is visited, it is empty, with no enemies or collectables. However, on when the party returns later in the game, the area will be filled with Selua enemies like the other two lungs, but collectables will only start appearing once the party moves into the Bionis' Interior via the Junks by speaking to Miqol. The party discusses the fact that the area seems much more alive on this visit than their first visit. This is due to the fact that Bionis has begun to awaken at this point, and thus the interior is filled with the organisms that live in any living being, albeit much bigger organisms due to the size of the Bionis.
