Fiery Dino Piranha is the fiery counterpart of Dino Piranha that appears in the Galaxy games. It is assumed that Fiery Dino Piranha is simply a slightly injured Dino Piranha. During battle, he leaves a fiery trail that hurts Mario/Luigi if touched.
In Super Mario Galaxy Edit
Fiery Dino Piranha is not encountered until Melty Molten Galaxy. Mario lands atop the egg of the creature just like he did with Dino Piranha but this time, the tail ignites and Mario must wait for it to simmer down before hitting it with a spin.
During the fight, the tail continues to flicker on and off, making the player have to think a bit more than with the normal Dino Piranha. After hitting Fiery Dino Piranha a total of three times, he will begin shooting fireballs from its mouth.
In Super Mario Galaxy 2 Edit
Fiery Dino Piranha is (if you count the special world) essentially the final boss featured in the sequel. He is fought in Boss Blitz Galaxy alongside his normal self. If Mario falls in battle while facing off against Fiery Dino Piranha, he must "re-fight" Bouldergeist.
