Blue Goo
Nickname for the Blue Potion. To be more specific, it’s usually used to refer to a Bottle filled with Blue Potion that is found in an item location. (the contents of each Bottle found are, of course, randomized)
Blue Potions refill both Hearts and Magic to full. The Potion Witch in the Light World sells it for 160 rupees so long as you possess an empty bottle.
