Armored Harriers

The Armored Harriers aka The Iron Adonis Twins first appeared in Paper Mario: The Thousand-Year Door.

Description
The Armored Harriers are ranked number 10 in the Glitzville's Glitz Pit. The pair are made of a type of metal that Mario cannot break through, and only with the help of a Baby Yoshi who is able to take an enemy into his mouth with his tongue and spit them back at the other enemy, was Mario able to defeat these two Iron Clefts. One of them wears red shoes, while the other wears green shoes, implying that the former is older.

Stats
HP: 6, Attack: 4, Defense: ???

Tattle: That's an Iron Cleft. That guy is SCARY. Period! What's WITH this book? It says no attack will work against Iron Clefts! It says nothing in the world is as an Iron Cleft, so its Defense is impenetrable. If that's true, the only way to beat one is to whack it with the other one... Running away may not be a bad idea at this point.
