Bob-omb Factory
Bob-omb Factory is one of the seven boards in Mario Party 9. The players ride in a legged machine. The mini-boss fought here through the boss castle is Whomp and the boss which is fought at the end of the factory and through the Bowser Gate is the evil Big Bob-omb.
Layout
The players start out in a room with lots of happening spaces. When those spaces are triggered, the conveyor belt moves the players around in the room. Once they get to the end of the room, there are stairs which lead the players to the boss castle where Whomp is fought. Once the battle is over, the players head through a pipe-like corridor. One of the gimmicks that happens through the factory is the Bob-ombs that fall on the vehicle when the captain lands on a happening space. The Bob-omb explodes making the player who landed on the space lose Mini Stars. One of the captain events is when the players hop of the legged machine and onto four square platforms. The platforms move forward through the corridor. If the player is lucky enough, they might get Mini Stars along the way. In the background of the factory, it shows how Bob-ombs are made. Once the players reach the end, they fight the boss.
Whomp Boss Battle
The players are on a rotating platform. Whomp is behind them. The players hit switches to rotate the platform and they try to avoid being crushed by Whomp. If Whomp misses he gets damaged and the players get points. If the players are unlucky enough, they will get hit and lose points.
Big Bob-omb Boss Battle
The players are on a big steel square and Big Bob-omb appears behind it. There are four different sizes of Bob-omb in front of him. The players must choose a size of Bob-omb to pick up and throw at the boss. The bigger the Bob-omb, the more points the player gets. But the bigger the Bob-omb, the more risky it is to get those points because the explosion might also damage the player making he or she lose points, so they must be wise.
