Pider

Piders are enemies in Paper Mario: The Thousand-Year Door. They live in the Great Tree and are the only known natural predator of Punies. As their name indicates, they are a spider-like creature, and just like everything else in the Boggly Woods, Piders are monochrome in color. It has two attacks. The first one involves spitting a ball at Mario, dealing 2 damage. The second one involves it spitting out three webs in quick succession, each one taking away 1 HP from Mario's HP bar. Like Scuttle Bugs, Piders have round bodies and suction cups on their feet. In the Glitz Pit, a Pider appears as one of the members of Mind-Bogglers. They also have stronger relatives known as Arantulas in the Pit of 100 Trials.

When Mario is leading the Punies, if a Pider is nearby several Punies will be frightened and run off, prompting Mario to defeat the Piders in order to move on.

Trivia

 * If there is an even amount of Piders in the battle, they will alternate between half being high up and half being down low. However, if there is an odd amount of Piders in the battle, they will all be at the same height.
 * If any Pider in battle is unable to move, all the other Piders will not move up or down.
