P-Flower

P-Flower is the Round 4 boss of Wario Blast: Featuring Bomberman!, formed out of the three Madbombers. It releases petals from itself to attack Bomberman or Wario. The petals can be destroyed by one blast from a bomb. Bomberman or Wario must defeat the boss by blasting it with bombs while P-Flower is firing its flower petals. After five hits, P-Flower is defeated and the protagonist moves to the next stage.
