Megaman X2 - Bubble Crab first

Megaman X2 is the only Megaman X game on the SNES where you don't have to backtrack to get everything in the game. While it is not necessary to do Bubble Crab first, I do so to show how it's possible to get everything in the stage without using bubble bubble shield. I also kill the robot fish.

The heart tank wasn't there because it took me a few tries to kill the fish that fast. I had a gameover. :P To get it, you have to wall jump at the top of the wall to clip onto the moving platform on the side.

The E-tank exploits a part of Megaman X physics where X jumps higher when he's running downhill then normal. You need to get onto the wall which isn't an easy thing to do. It still takes me a few tries to do it myself.

Bubble Crab himself is a pushover. Mash the fire button whenever he brings up the bubble. You can also jump over him and most of the time he'll fire his head things which will remove his bubble. I never had to deal with his little bubblings, yay!
