Recurring Enemies in The Mario Series - Blooper

Blooper

Bloopers (Gessō (ゲッソー?) in Japanese, originally known in English as Bloobers) are white, squid-like creatures that first appear in Super Mario Bros. that live in water.In some Mario sports games, the Mario Kart series and Super Mario Sunshine, they are items that can be used by players. In Mario Kart, they temporarily reduce drivers' visibilities by spraying ink on them, blocking most of their view. They also appear in the Manta Rings mini game in Mario Party 4. Blooper is also an unlockable playable character in Mario Party 8. To unlock it, the player has to beat the Star Battle Arena once. It was also an unlockable character in Mario Super Sluggers. Two variations of Blooper appear in Mario and Luigi: Bowser's Inside Story: the "Bubble Blooper" and the "Dried Blooper".

GameDaily listed Blooper as the twentieth best Mario enemy, describing it as a difficult enemy to out-swim.
