Paper Mario Wiki

Gooper Blooper is a recurring boss in the Paper Mario series. He is a large Blooper with long, noodle-like tentacles. Gooper Blooper is known to squirt an excess of ink onto its adversaries.


Paper Mario: Sticker Star

Gooper Blooper appears in Paper Mario: Sticker Star as a boss, marking his first appearance in the Paper Mario series, he is the main boss of World 3 and is overall the fifth boss of the game.


Gooper Blooper used to be a music-loving Blooper until a Royal Sticker landed on him and turned him and all surrounding Bloopers into Poison Bloopers. He is the source of the poison that plagues the forest.


In battle, Gooper Blooper's attacks are determined according to the music. In the beginning, he will start off with a double slap using his front tentacles. After that, he will use his back tentacles for a considerably weaker double slap. Once the music changes again, Gooper Blooper can slap with all four of his large tentacles. When the music changes once more, Gooper Blooper will turn dark purple, signifying he is about to spray Mario with poison. If Mario is hit with this attack, he will be poisoned for four turns. As well, parts of the screen will be covered in goop. Oddly, when Gooper Blooper is poisoned by his own attack (if you use the sponge before he spits poison at you), the battle music changes into a remix of the Super Mario Bros. theme. This game is the first time that Gooper Blooper speaks with dialogue.

At the end of battle, depending on how fast it took you to beat this boss, Kersti will appear to tell you that the battle took you a lot of stickers to beat. This boss is hard but if you used the sponge sticker when he is about to spit poison at you, things are easier.

Paper Mario: The Origami King

Gooper Blooper reappears in Paper Mario: The Origami King as a large Paper Macho boss. It is the first Paper Macho boss Mario encounters, the first boss of Chapter 3 and is overall the 5th boss of the game.

Paper Macho Gooper Blooper

Gooper Blooper appears on The Princess Peach during the quest to save Olivia after her entrapment under a huge rock in the Yellow Streamer section of the game. It is fought on the overworld on the bow of the ship and has an attack where it slams its tentacles down creating shockwaves. Once you hit the weak spots on all the tentacles, it jumps onto the boat and starts shooting water at you. Its last weak spot is its right eye.

In Bobby's memory scene, it is shown that the Gooper Blooper is why Bobby lost his fuse and his memories.


Gooper Blooper has a variety of attacks. In its first form, it will mainly attack by slamming its tentacles down on the ground, creating water shock waves. It can also launch out ink from its mouth to hinder Mario. In its second form, it gains the abilities to and launch a barrage of water shock waves.


First Phase

Wait until the Paper Macho Gooper Blooper slams one of its tentacles on the ground, jump over the shockwave, then attack it with your hammer to damage it. After taking out four tentacles, it will spew out ink to hinder your movement.

Second Phase

After taking out all four of its tentacles, the Gooper Blooper will then jump and land on top of the Princes Peach to fight Mario directly. In the second phase it will use the same attacks, except it will also perform a spin move that will also launch out shockwaves. The strategy is to wait until the Paper Macho Blooper is tired out from the spin move, then hit the weak spot on its right eye. After that, it will perform another spin attack, then it will stop and slam both of its tentacles down to create a shockwave. Hit the Paper Macho Gooper Blooper with the hammer five times to defeat it.


  • In all of the appearances in both Paper Mario games, Gooper Blooper is always:
    • In the third Chapter.
    • Fought as the fifth boss.
  • In Paper Mario: The Origami King, the battle with the Paper Macho Gooper Blooper is very similar to the fight with Glooper Blooper in Super Mario Sunshine. Both battles involve taking out the Blooper's tentacles and then going after the head.
