Puniper is a large Puni that lives in the Great Tree in Paper Mario: The Thousand-Year Door. When Mario first meets him, Puniper doubts that Mario can save the Punis. Even so, he eventually gains respect for Mario, and recognizes him as both a hero and leader.
Puniper is a very rude Puni as, even after he was saved by Mario and Punio, he didn't want to go with them further into The Great Tree. However, he was set straight by the Puni Elder and Puniper temporary joined Mario's side.
- Puniper is the largest out of the Punis as he is nearly Mario's height.
