Bombard King Bob-omb

Bombard King Bob-omb (also known as Bombard Big Bob-omb in Europe) is a boss minigame in Mario Party 9. The gameplay of this minigame is similar to that of Same Is Lame, from Mario Party 6.

Introduction
The camera shows the front of the platform, where Big Bob-omb is raised into the room.

Gameplay
The objective of the game is to defeat Big Bob-omb by tossing normal Bob-ombs at him. Normal sized Bob-ombs are worth one point, the medium Bob-ombs are worth two, and the big ones are worth three. Every turn, four Bob-ombs are transported onto the platform via conveyer belts, and players choose which one to toss by pushing one of the buttons shown; however, if two or more players pick the same bomb, they will run into each other and be temporarily dazed, preventing them from throwing one. Once Big Bob-omb loses half of his health, he will toss Bob-ombs at the players who fail to throw a Bob-omb, causing them to lose one point.

When two players are playing, Big Bob-omb also has the opportunity to pick up a Bob-omb. While his health is in the green section, he will simply throw the Bob-omb backwards and disallow the player from throwing it at him. However, if his health has reached halfway and this happens, Big Bob-omb will instead throw the Bob-omb at the players, causing them to lose 1, 2, or 3 points, depending on the size of the Bob-omb that he throws.

The player who lands the final attack will earn an additional three points, and the player with the most points wins the minigame.

Ending
Once Big Bob-omb is defeated, he will explode, revealing several Mini Stars.
