A Fire Ninja is a penguin who has mastered the art of fire. This means that a player has beaten the game Card-Jitsu Fire.
How to become one
The more experience a player gains as he/she progresses through the game, the more fire items he/she receives. Once one has obtained all of the items, he/she must defeat Sensei to get a Fire Gem for the Amulet.
As a Fire Ninja, a player can light up the fire tile in the Ninja Hideout. They can also hold fire in their penguin's hands by wearing the complete suit and dancing. By waving, they can disappear in a wave of fire.
