Deburina, or Pig Ballerina, is one of the many enemies in the Game Boy Advance platform game, Wario Land 4. They only appear in the level Doodle Woods. In some parts of this level, there are drawings of Deburinas on the wall, and some drawings come to life when Wario either gets near it or walks under it. They are depicted as a dancing, female hula-hooping pig. Deburina will slowly dance towards Wario, intending to damage Wario by grazing him with the seemingly dangerous edge of the hula-hoop. Deburina can not be attacked from the side while she is dancing, because the hula hoop would harm Wario. Wario can only defeat them by a ground pound on the head.
If the player does a standard jump and lands on a Deburina's head without doing a ground pound, then Deburina will fall to the ground, the hula-hoop will stop spinning and fall with her, and she will start to cry. She will then be completely defenseless, and she will be no longer immune to side attacks. However, if Wario leaves her alone for a while, then she will soon get back up, and start dancing again.
