Dongorongo

Bongorongo is a Dodongo-like Boss in The Legend of Zelda: Phantom Hourglass. Link enters a room with sand surrounding the center platform. Link cannot cross the sand, as there is no bridge. However, a door opens in the back and a young Goron, named MaiGoron, who is being held prisioner by Bongorongo comes out. The objective is to roll into Bongorongo's belly with MaiGoron, turning him over. Then, Link must use a Bombchu to damage it by drawing a line into it's mouth. After doing this twice it appears to be defeated, as a bridge appears and MaiGoron walks out of the room. However just as Link crosses the bridge, Bongorongo wakes up, and some of it's armor breaks revealing a weak spot. It attempts to inhale Link. This is your opportunity to throw a bomb into its mouth, and attack the weak point. Do this a few times, and the Heart Container, some more Sands of Time, and an odd, red crystal, possibly called "Scarlet Steel".
