4-5 - In this upper-left room, Iron Balls will fall in each corridor as long as Bomberman is nearby. They fall from the empty end of each hall toward the pit at the other end.
4-6 - The switch will need to be blasted twice in order to progress further into the cave. After it has been blasted once, Bomberman will need to place the second bomb and run past the obstacle in the middle of the room before it is raised by the resulting explosion.
4-7 - Tinklebear is faced here.
4-8 - The switch will only lower the obstacles for as long as a blast is hitting it. Thus, either the Long-fused Bomb or the Remote Control must be used in order to delay the blast and allow Bomberman to get to the obstacles in time.
