|| This ugly, red Dull Bones is stronger than a normal Dull Bones. Even if its HP drops to 0, it can come back to life.

|That's a Red Bones! A little TOO red, I think. No fashion sense, y'know? Unlike your average Dull Bones, even if you pound it to O [sic] HP and it crumbles... It totally might revive! Like a zombie! My advice is to get rid of all the Dull Bones, then attack the Red Bones. Oh, and one more thing! Once its friends start to fall, it may create some more!

“You'll go no farther, and from this moment on... You'll be nothing but bones!”
—Red Bones, Paper Mario: The Thousand-Year Door
Red Bones are stronger than Dull Bones but not as strong as Dry Bones. They act the same as others in the Bones family, except Red Bones seem to summon Dull Bones more often. They're the only ones with blue eyes, and they seem to be able to command Dull Bones. As stated above, they can create new Dull Bones, which can make battles cumbersome. They only appear in Paper Mario: The Thousand-Year Door, where they are present only in Hooktail Castle and a certain puzzle in the Palace of Shadow's Riddle Tower.
