4D bullies are the fourth dimensional counterparts of the bullies, bob-omb like creatures with horns, that serve Bowser. They, like any other fourth dimensional enemy, work for Dimentio. They have the same function as bullies, as hitting into people, bumping them backwards. They are a little different compared to the bullies in the Mushroom Kingdom. They have pink horns instead of yellow, and instead of serving a Big Bully, they serve a bigger version of themselves, the D-Bully. The D-Bully is the 4D counterpart of Big Bullies. It is unknown if their real naming is a "Bully".
