Mogu Mogu no Mi

The Mogu Mogu no Mi, also known as the Mogu Mogu Fruit, is a Zoan type Devil Fruit that gives it's the power to become a mole. The affected person will then be able to attack their enemies with mole-claws the size of bananas and move underground as most people do through water. Mogu is short for "mogura," the Japanese word for mole. It can also be short for "mogumogu," a phrase meaning to chew one's words, which describes Miss Merry Christmas' manner of speech. In the 4kids dub, it is called the Diggy Diggy Fruit. It was eaten by Miss Merry Christmas.

Strengths and Weaknesses

 * Banana-sized claws for slashing
 * Ability to dig underground with such speed and skill that it's like swimming in a pool to the user, and a powerful enough user will just smash through any stone structures in their way without losing any speed.
 * Same main weaknesses as other Devil Fruit users.
 * If the user of this fruit's power is on the roof of a building, aboard a ship, or in some other place where he/she can't tunnel underground, then their abilities will be greatly impaired.

Usage

 * Mogura Tonpou: Mogugyo (Mole Digging Technique: Mole-Fish)/ Woodchuck Swimming Stealth Style: From the opening of one of her molehills, Miss Merry Christmas leaps into the air & swan dives underground.
 * Mogura Banana (Mole Banana)/Woodchuck Banana: Miss Merry Christmas attacks her opponent with her half-mole form's claws. This attack can be done from underground while close to the surface or by leaping out at her opponent.
 * Mogurazuka Highway (Molehill Highway)/Woodchuck Highway: Off & Running: Miss Merry Christmas grabs her opponent's feet from underground & starts tunneling rapidly, dragging him/her along the surface with her.
 * Mogu Mogu Impact/Woodchuck Wallbanger: After performing Mogurazuka Highway, Miss Merry Christmas steers her opponent into a wall, smashing him/her into it with great force.

Translation and Dub Issues
In the 4kids dub, in order to match with the Miss Merry Christmas' name change to Miss Groundhog's day, the animal with which the fruit allows her turn to was also changed. The animal which she turns to was changed from a mole to a groundhog. This change also included changing Usopp's penguin assumption regarding Miss Merry Christmas' hybrid form. This change however was only dialouge-wise. Despite the dub stating she was a groundhog, she still looked like a mole.
