Bombermen enter the arena again and this time you have a choice of character: Tomato Guy or Pirate King. Once you've made your choice, go directly to the first available jungle location and complete all the levels. To do this, you need to leave bombs behind you so that the enemies that are on the level are blown up on it. When you destroy everyone, you will move to a new level, but only after the lock icon appears. Collect trophy bonuses left by the villains and use them to advance in the Boom Battle Arena.
