Bubble Bloopers are big, blue sub-species of Bloopers found in the Pump Works area in Bowser's body in the game Mario & Luigi: Bowser's Inside Story. When there is no water, they become dried up and are then known as Dried Blooper. They attack Mario and Luigi by rolling and can be counter-attacked by using a hammer. When they are dry, they just attack by floating at Mario and Luigi. When it goes to the top screen, left or right, it indicates which bro. it desires to land on.
- Bubble Bloopers resemble Blooey, Luigi's partner from Paper Mario: The Thousand-Year Door.
- The Dried Blooper also resembles Bowser Jr.'s version of the Super Blooper from Mario Kart Wii or the Glad Blooper from Super Princess Peach.
