Uh... it isn't in a large map, like an Abyss, or the Veil, and it really doesn't have a name other than Face Worm Cave (just made that up). It is not the final boss; just an appetizer along the way while exploring the Sunset map (same as Beauty of Aquaria with different stuff). We will not have a series of final bosses. Making bosses is really hard, especially when you are a perfectionist like Yogoda; both of us want to do something different other than copy the bosses from Aquaria. Our mod will only have four bosses. We borrowed this one and did no modifications because this is for people curious enough about Aquaria to have found this unused boss while browsing the entities in the main game folders and wanted to see it in action, unmutated. Seriously, a big worm with lots of voracious pink faces you have to kill one at a time is not something you run into on the street, or even on Fringe. Mutant enough for me.... but you are welcome to play with it; all the graphics and codes are there in Aquaria.
