Big Blooper

A Mega Blooper is a giant version of a Blooper that first appears in Dance Dance Revolution: Mario Mix.

Dance Dance Revolution: Mario Mix
A Big Blooper appears as in Stage 2-4. After entering the whirlpool in the SS Brass, Mario/Luigi and Toad enter a temple which holds the next Music Key. Big Blooper guards it, so Mario/Luigi must face it in a dance-off. During the music, Blooper Bop, mini-Bloopers and Big Blooper's tentacle are additional steps alongside the standard arrows. Missing the mini-Bloopers will cover the bottom of the screen with ink, giving Mario/Luigi less time to see the arrows. Big Blooper's tentacles also rise up from the bottom of the screen at a faster speed that the mini-Blooper, and on harder difficulties, more than one tentacle rise at once. The tentacles must be repelled by stepping on them so the player does not lose points.

Mario Party 9
While not named as such, a predecessor to Mega Blooper appears in Mario Party 9 in a boss minigame, Blooper Barrage.

Mario Party 10
In Mario Party 10, Mega Blooper is fought at the end of Whimsical Waters, in a castle, in the minigame Mega Blooper's Bubble Battle. Mega Blooper causes bubbles to rise, and these bubbles contain half a picture. In the bottom of the screen, a static picture or more shows the other half. Players must choose the correct half in a bubble to deal damage to Mega Blooper and earn a point. Mega Blooper can disrupt the fight by splashing ink on the screen. At half health, it becomes enraged. It can swim rapidly in a circle to make bubbles more confusing and harder to hit while also spawning Bloopers to attack players that have matched their cards incorrectly. The player who deals the final hit to Mega Blooper earns an additional five points and defeats Mega Blooper.

Mario Party: Star Rush
Mega Blooper reappears in Mario Party: Star Rush again as a boss. Players engage it in any board and at any time, provided they land on the boss space. Mega Blooper is a less aggressive boss in its minigame, Mega Blooper's Bayside Bop. Instead, it plays as a role of a conductor. It summons Bloopers depending on the amount of players participating and it throws a beach ball. The Bloopers hit the beach ball in specific rhythm. The Mega Blooper then throws another beach ball. To earn points, players then have to time hitting these beach balls the same way the Bloopers have done. After they are done, the players randomly shift positions. In the second half of the minigame, the Mega Blooper increases the tempo. The player that deals the last hit to empty the meter earns an additional three points. After the minigame is finished, Mega Blooper finishes conducting and leaves.

Super Mario Party
Mega Blooper makes a cameo in Super Mario Party as a non-playable character.

Super Mario Maker series
In Super Mario Maker, Super Mario Maker for Nintendo 3DS, and Super Mario Maker 2, Mega Bloopers appear as Bloopers that can be enlarged with Super Mushrooms. They act the same as regular Bloopers, only bigger.
