Mouse Ball of Fur

Mousy Wool Clump is an offensive Fire-element ninjutsu. Its result is self-guiding burning projectiles that explode upon touching anything. The mechanism is as follows: the user's saliva turns into a blazing wool clump, whose appearance resembles a mouse. Then this clump sequentially disintegrates into many separate burning fragments. Each of them independently pursues the target, after which it detonates.
