Spewart

Spewart is a member of the Broodals. He has two known boss fights, one in Luncheon Kingdom and one in Wooded Kingdom.

Battle
In battle, Spewart can spit poison. At the beginning of each round, Spewart will surround himself with his poison, then start going after Mario to spit poison at him. Mario must use Cappy to knock Spewart's hat off, then jump on him for damage. After that, Spewart will fly around in a saucer fashion and cover the field with his poison. After being jumped on three times, Spewart will fall in defeat.

Trivia

 * Unlike Topper and Harriet, who either get stunned or panicked when their hats come off, Spewart will continue chasing Mario even if Mario knocks off Spewart's hat.
 * When Mario jumps on Spewart, every bit of poison on the field at the time will clear out.
 * Throwing Cappy over Spewart's poison can clear out some of the poison.
