Spewart
How to Beat All Darkside Bosses in Super Mario Odyssey
Spewart may look the most intimidating out of all the Broodals but he soon exposes himself as the easiest of the bunch to take down. Spewart will begin the fight by, well, spewing purple goo all around him. All you have to do it throw Cappy into the goo and it will clear a path through. Walk through the path and hop on his head and it’ll cause him to retreat into his hat for the second phase of his attacks. Spewart will start sliding across the arena, leaving purple goo behind him. All you have to do is pick a spot, stand there, and throw Cappy at Spewart whenever he gets too close or starts heading in your direction. This will cause him to change paths until he’s done with his purple goo spewing tirade. He will return to the center of the stage and repeat the exact same process all over again.
This one will be a quick and easy fight.
