Jump and dash to the wall to your left, where you will find an alcove blocked with blocks you can use your Boots to destroy. When you reach a platform with a Metool on it, kill him and go to the left of that platform. Climb to the area above the Heart Container's location, and instead of heading right where you would go if you wanted to continue along with the stage, instead head upward and leftward. You'll need the Boots in order to do an jumping dash and also in order to kick through the bricks that'll block your way. Located in the second part of Flame Mammoth's stage, in the area above where you obtain the Heart Container in that very stage, the final Sub Tank in the game (if you're following our order) can be obtained. Thereafter, jump into the void left by the open glass and grab the out-in-the-open Sub Tank! Eventually, some platforms moving up and down will catch your attention, and while you're supposed to ultimately take them to your right, you can take them up and to your left as well, where some glass can be broken with a simple firing of your X-Buster. It's located near the beginning of the stage, after going upwards at the beginning and then rightward over the 'Airport 1001' sign, et cetera. Nothing is needed to get the Sub Tank, but due to the late nature in which we get to Storm Eagle's stage (if you follow our boss order and flowchart), you won't actually get a chance to get it until some time into the game. staying still and firing will get you no where). To get it, use the Boomerang Cutters (but jump and then fire so that the Cutters go down and grab the Sub Tank. but instead, look to your right, and in the corner of the screen you'll spot the Sub Tank we seek.

At this point, you'll eventually run into another ladder leading up. In the very beginning of the stage, go forward and then when you come to a ladder leading downward, take it and continue rightward.

To obtain this Sub Tank from Spark Mandrill's stage, you'll need to return to the stage with the Boomerang Cutters after you defeat Boomer Kuwanger (that is, if you're following our flowchart and order). When you do this, the 'lair' where the Bulldozer was sitting before will now be empty, and you can grab the Sub Tank you find there! Quickly go down low enough to activate it, then climb back upwards and let it pass underneath you. You'll spot an enemy Bulldozer to your left. Here, cling to the left wall and slide downward. I looked at a walkthrough video and they had a 'M' option in their start menu and could shoot ice Close. After the initial part of the stage where you are literally catapulted down the hill via the metal slide thing (whatever you want to call it), you'll continue rightward and then be able to head downward. To grab the first of four Sub Tanks in this game, head to Armored Armadillo's stage.
