The Tables Have Turned
After complete and utter destruction, Goomboss is reborn in Goomsday Wii. A regular Goomba is knocked into a magical cauldron and is turned into the leader of his people. After knocking Bowser off the throne, Goomboss gets his hands on the Scepter of Superiority. Intending to make his army of thousands into an army of trillions, Goomboss discovered that he needed a Mega Mustache in order to wield the Scepter's full potential. He was thus forced to wait while the Magikoopas performed their magic on his facial hair.
Goomboss is the Fortress Boss of World 1 in Super Mario Bros. Ultra. He works for Larry Koopa. You defeat him by first killing all the Goomba's he throws to you, then the Grand Goomba's, then the Mega Goomba's and then Goomboss himself.
Goomboss appears in a mission in Mission Mode. To complete the mission, you must throw the basketball at Goomboss. This takes 10 hits to knock him out (5 with the Golden Ball). When you throw the ball, Goomboss will try to bite the ball then shoot it off his sharp teeth. You have to dodge the ball, but it's shot at blazing speed. You have 2 minutes to complete the mission and you have 3 lives. This mission is easiest completed with the Golden Ball.
Goomboss is fought in Goomba Fields as the second boss in the game. He boasts low HP even for the point of the game he's fought at. Goomboss only has 36 health.
Goomboss reappears as the boss in the Jumbo Giant Galaxy. His battle takes place in a large room with giant blocks. In the fight you must grab the Spring Mushroom, powerbounce up to him, and ground-pound him. After one hit the block he stands on rises, and yellow elevating platforms appear. You must get on one and repeat the process. Then the block will get higher and more moving platforms appear. Hit him once more and you get the Ultra Star.
Behind the Boss Door in Mushroom Kingdom Way is a Goomba that Bowser transforms into Goomboss. The boss fight is similar to the fight done in Super Mario 64 DS, but with an added twist: the boss is protected by a shield and can only be harmed when the shield is destroyed. Destroying the shield is simple; a bomb must be thrown at the shield. Afterwards, Goomboss is vulnerable. After each hit, the shield is regenerated, but in a different color. Blue is the weakest, yellow is in between and red is the strongest. Once Goomboss is defeated, he pops into dust, opening the path to Toad Town.
