Moon Cleft

Moon Clefts are a very powerful lunar species of Clefts found in Paper Mario: The Thousand-Year Door. Aside from the increase of power, they look and act nearly identically to normal Clefts. Moon Clefts are found during the portion of Chapter 7 that takes place on the moon. These Clefts have high statistics but are easy to beat when an explosion, such as from Admiral Bobbery, flips them over, lowering their Defense down to 0. Like their relatives, they disguise themselves as rocks, but they reveal their true form when Mario comes close enough. Moon Clefts attack by charging at their opponents, and cannot be stomped because of their spikes. This enemy has colors similar to a normal Cleft from Paper Mario, whereas those are pale gray in Paper Mario: The Thousand-Year Door in fitting with the color scheme of Boggly Woods. Their tattle also states them to simply be a basic Cleft found on the moon. They have the highest defense power in the game, alongside Chain Chomps and Elite Wizzerds.

Trivia

 * The respective internal file names for Moon Clefts and normal Clefts in Paper Mario: The Thousand-Year Door indicate that at some point in development, Moon Clefts were intended to be the "base" version of Cleft while the final game's normal Cleft was intended as a variant, explaining Moon Cleft's usage of the original coloration.
