Tattle	That's a Bald Cleft. Basically, a rock monster with a swarthy-looking face. Uh... this is kind of mean, but bald guys... really just don't do it for me. Yeah. This guy is rock solid. Fire doesn't even hurt it. It might be best to attack with, say... a POW Block.

Bald Clefts are rocky enemies introduced in Paper Mario: The Thousand-Year Door. They can be found on pedestals in Shhwonk Fortress, during Chapter 1, and attack by charging at Mario and his partners. Because Mario faces them so early in the game, there are limited strategies to pierce their high defense. The best and most effective strategy is to use a POW Block on them or a special Badge.

Bald Clefts appear again in Super Paper Mario as enemies in the Yold Desert. Like their relatives, they disguise themselves as rocks, and reveal their true form when Mario gets close enough. They attack the same way as they did in Paper Mario: The Thousand-Year Door. However, the Super Paper Mario variety aren't as tough as their other Paper Mario counterparts, as they can easily be defeated with Boomer. None has the ability to flip dimensions.
