Fracktail

Fracktail is the first stage boss in Super Paper Mario.

Attack Strategy
In order to defeat Fracktail, Mario must flip into 3D then jump on top of its long back when the robot glides low. The battle scene will then shift to the back of Fracktail's back as he flies. Players must then pick up a Frackle  crawling around on its back using Thoreau and throw the Frackle at Fracktail's weak point which is its antenna. After taking three hits, Fracktail will perform an aerial loop. Mario must jump from the tail at the end of the loop back onto the head; failing to do so will result in falling to the ground and having to dodge Fracktail's attacks until the chance to jump onto its back arises again.

Fracktail must be hit in its antenna nine times, and upon being defeated, its personality briefly returns to normal. It apologizes for its error in attacking Mario and pleads that he save the world, and then it explodes.

Tattle
That's Fracktail, the robotic gardian of the Pure Heart. It's quite enormous... Max HP is ??. Attack is 1. It can fly and swoop down with its big, open mouth... But I think the attena like horn on its head is its weak spot... I think you're going to need to use Thoreau to hit it...
