Mario together with Mallow and Geno can take down ol' Yarid. The Water Blast can be devastating, so watch out! Mario should have the Amulet, Geno the Safety Badge, and Mallow the Safety Ring. When Yaridovich uses the Mirage Attack, attack the one that takes less damage. Yaridovich's main attack involves pulling his head off and poking you with it. Scary! But he's not so hot. You'll get 'im with Super Flames and Jumps, Shockers, and Geno Whirls and Beams. (Note: use the Geno Beam if you just can't time the Whirl right.)
