Bubble Armor (sometimes called Bubble Gear) is used as an item that usually grants Water-Breathing. It is usually gotten before an aquatic level, making it coincidental. It is unimportant if you actually equip the item, as simply having it grants water breathing, even though you usually can't go into water without it.
Editor's Note: Bubble Armor is probably based off of the item in Soul Blazer.
Bubble Gear is given by Kracken. He gives 5, and he is on the beach before the Water Shrine.
