Red Bubble

The Red Bubble is a disembodied skull with red flames surrounding it. They usually stalk places where heat is abundant, and can ram into opponents, setting them on fire in the process. The best option is to use a shield of some sort to block their attacks. This will remove their red flames, leaving the skull vulnerable to attack. Slicing the skull with something like a sword will cause the death of the beast. Red Bubbles have been spotted in all of the current 3-D Zelda games: Ocarina of Time, Majora's Mask, and Wind Waker. Their overall appearance hasn't changed very much throughout the games, although the Wind Waker incarnation has a distinct laugh that the other two incarnations don't have.
