Anyhow, the fact is that with the laser in Vanilla the fight is broken; it's a major endurance test. So, go ahead and accept you will have to deal with the time out cubes. The main key to dealing with them is honestly to just not focus on them too much, don' attempt to shoot them down, just let your missiles do the job for you. For the most part if you don't let them get you from behind you'll be alright.
THANK YOU! I knew the biggest fan with access to all the machines around his homeland would be able to pull a miracle with the least likely setup. I haven't been using my Missiles at all, I've been trying to shoot the cubes before lining myself up with Glutton's offspring, preferably not giving that cute nipper a kiss in the process.
I'll have to override my savestate, as I've been practicing without a shield. That would make for one hell of a show if I can accomplish this feat without taking any shield hits at all....
I never knew you didn't have to SHOOT the miniature fish! That changes everything, I kept concentrating fire on those instead of hitting Glutton himself. Thanks for all your advice, I'll do my best.
