Grab the Fire Bottle immediately and retreat to the floor of the area. Now two strategies exist here, both with pros and cons. The aggressive approach is to jump up to a ledge equal to the flight of the Giant UFO, followed by using the rapid fire droplet shot to land 15 hits to defeat the saucer. The more passive approach is to remain on the ground, creating fully Charged fire droplets, letting the Giant UFO attack the spot where you are standing, moving to the side and laying it down behind you to damage the odd creation (land 5 hits to wipe it out for good). No matter which way you do it, collect the Items for points before being sent to the next imperiled world!
