Uploaded January 2026 | Updated September 2026, 16 hours ago
An underwater level inspired by SMW's Vanilla Fortress with Fishbone, Bony Beetles, Thwimps and a couple of SMB3 enemies of Dry Bones and Thwomps. First area is SMBTLL's World 8-1 underwater level on the famicom due to the tile change oversight but SMAS constructed it much differently. Level ends with Boom-Boom.
