Conkdor

The Conkdor is a new type of enemy that first appeared in Super Mario 3D World. These enemies stand still, waiting for the player to happen by. When the player gets close enough, it "conks" its beak on the ground, which will damage the player. However, doing this leaves their neck and head exposed, and both can be jumped on to defeat the enemy. Conkdors can also rotate, following the player. Their beaks can also be used to break stone blocks.
