Head Thwomp

Head Thwomp is a specific Thwomp from The Legend of Zelda series, and a boss in The Legend of Zelda: Oracle of Ages. Head Thwomp is the second boss, and it is fought at the end of Wing Dungeon. Head Thwomp has four faces (an evil grinning blue, a grumpy purple, an angry green, and a surprised red), which it rotates through rapidly. When a bomb is thrown in its open head, it will spin furiously and land on the same face as when the bomb landed in it. It will then perform a function specific to that face: the blue one will shoot rotating energy balls that orbit in wider circles until they leave the screen, the purple one will smash into the ground, the green one will spit Podoboos across the stage, and the red one will cause damage to itself. The objective is for Link to hit the red face four times, which will destroy Head Thwomp for good.
