Mega Blooper's Bubble Battle

Mega Blooper's Bubble Battle is a boss minigame appearing in Mario Party 10. It takes place in Whimsical Waters and pits players against Mega Blooper.

Introduction
The minigame takes place around a chasm at the bottom of the ocean. As the players float near the sea floor, Mega Blooper rises from the chasm, ready for battle.

Gameplay
Bubbles will rise from the chasm around Mega Blooper, each carrying half of a picture inside it. Players must choose a bubble with a picture half that correctly completes the picture at the bottom of the screen. A successful match allows the player to fire the picture at Mega Blooper (gaining two points in the process), after which a new picture appears. Sometimes, multiple half-pictures will appear (up to four); all must be completed before a new set will appear.

As the minigame progresses, Mega Blooper will try to confuse the players by releasing ink over the chasm to obscure the bubbles. After losing half of its health, it gains the ability to swim in a circle, carrying bubbles in its wake; this temporarily makes the images harder to see and the bubbles themselves harder to hit. It also summons a swarm of regular Bloopers; anyone who makes an incorrect match at this point will be attacked by a Blooper, losing one point.

The minigame ends once the Mega Blooper's HP drops to zero. The player who lands the final blow gains an additional five points. After the Mega Blooper sinks back into the chasm and explodes, the result screen is shown with a sum of points, penalties, and bonuses. The player with the most points overall wins the minigame.

Ending
After gaining the last hit, the Mega Blooper spins right to the bottom of the water and then explodes.
