Fiery Dino Piranha

The Fiery Dino Piranha is a boss fought in Super Mario Galaxy and Super Mario Galaxy 2. The character is another type of Dino Piranha. Its body is dark red, and its head is black with red spots, much like its egg. Its petals are similar to that of a palm tree, and has white lips, like the normal Dino Piranha, but in contrast to the green lips of Petey Piranha. As it's tail is on fire, it can leave a fiery trail behind it, and, in its final form, it is able to shoot fireballs. It's also much faster than the normal Dino Piranha, which makes it harder for Mario to strike its tail. The player can catch up with it by long jumping.

Super Mario Galaxy
In Super Mario Galaxy, Mario will battle this boss in the Melty Molten Galaxy. This battle practices the use of the Spin. The beginning of the battle is much like that of the normal Dino Piranha, with Mario landing on the egg and a blind boss trotting around the planet, except the bulb of the tail will ignite and go out in a steady rhythm, forcing Mario to wait until its tail is out before breaking the egg completely.

Once the flaming boss emerges from the egg, it will spot Mario and chase him, just like the original boss. However, the bulb's fire will still flicker on and off, again, forcing Mario to wait until the tail is out before striking. This can be tricky, because someone who is chasing the Fiery Dino Piranha might find themselves running right into the trail of flame that the bulb creates.

After the first strike, the boss will stomp in anger, and with a swoosh of its fiery tail, continue chasing Mario. After the second strike, the flaming boss will begin shooting fireballs out of its mouth, making the planet arena a much more fiery and dangerous place to walk around. The player must dodge the fireballs and the trails they leave, plus the trail the tail's bulb leaves, and, to many players' frustration, wait until the bulb has lost its fire before delivering the third and final strike. The boss will ignite into flames once more in a cry of agony before falling dead to the ground and vanishing in a poof of smoke.

Super Mario Galaxy 2
Fiery Dino Piranha does re-appear in Super Mario Galaxy 2. It is the last boss Mario fights in Boss Blitz Galaxy. Its battle is the same as the one from Super Mario Galaxy. He is the last boss of the game.

Trivia

 * The Fiery Dino Piranha shares its music with the normal Dino Piranha, as well as Tarantox.
 * Fittingly enough, Dino Piranha is the first boss, while Fiery Dino Piranha is the last boss (not counting Bowser from Bowser's Galaxy Reactor), creating the feeling of having gone full circle.
 * Fiery Dino Piranha could be considered the true final boss of Super Mario Galaxy and Super Mario Galaxy 2, because it is the last boss that appears in the sequence of the levels in both games. This also means that Fiery Dino Piranha could be considered the true final boss of the whole Super Mario Galaxy series.
