King Bob-omb's Boom D'état

King Bob-omb's Boom D'état is a Boss Battle minigame in Mario Party: Star Rush. Its name is a word play on the phrase coup d'état, which refers to an illegal and often violent transfer of state power.

Gameplay
King Bob-omb spawns Bob-ombs. The ground is marked with red cross-hairs to indicate where they will land. If any Bob-omb falls directly on a player, it immediately explodes and stuns them, making them lose a point. Once the Bob-ombs have landed, players can carry one by standing near one and pressing. Bob-ombs eventually explode, but some Bob-ombs explode earlier than others. Any players caught in the explosion are momentarily stunned and lose one point. To earn points, players must stand near a cannon and press to place the Bob-omb in the cannon. The cannon then launches the Bob-omb and damages King Bob-omb and gives the player one point. Cannons can use only one Bob-omb each; if a cannon loads and launches a Bob-omb, it then disappears.

At half health, King Bob-omb becomes enraged and spawns more Bob-ombs. Some Bob-ombs, however, are large and score three points. They are, however, heavier, so they limit movement. The player that deals the finishing blow to King Bob-omb earns three points. The players with the most points win the minigame.
