Biography
While searching for Oogtar the caveboy in the Enchanted Forest, Luigi accidentally bumps into Wizardheimer. Luigi apologizes by addressing him as a regular Koopa Wizard, but Princess Toadstool corrects him claiming that the wizard is Wisenheimer, the most terrible Koopa Wizard of them all. Wizardheimer shouts out his correct name with a bolt of lightning, which scares away Yoshi. He then orders Mario, Luigi, and Toadstool down a Warp Tube to his haunted house, threatening to use a Bob-omb on them if they refuse. After they jump in, Wizardheimer follows them in, where he shackles the trio in the basement. Toadstool demands to know what Wizardheimer wants from them, which he coldly remarks that being evil is simply his nature before leaving.

Meanwhile, after Yoshi saves Oogtar from Piranha Plants and a Wiggler, he tells the caveboy about Wizardheimer kidnapping the group and imprisoning them in his house. Dauntless, Oogtar marches over and knocks on the door, to which Wizardheimer tells him to scram. Oogtar demands to be brought to his friends. Wizardheimer sarcastically agrees to Oogtar’s request by warping the caveboy to the basement and chains him up as well.

Now realizing its left to him to save his friends, Yoshi muscles up courage and rushes inside the haunted house, past Wizardheimer’s traps and ghost minions. On the basement stairs, he is attacked by Wizardheimer himself, shooting Yoshi with magical spells. From advice by Oogtar to use his tongue, Yoshi snatches Wizardheimer’s wand and eats it, leaving the Koopa Wizard powerless. Wizardheimer demands Yoshi to spit back up his wand, only for Yoshi to belch out a blast that cuts the prisoners’ restraints. The now free Mario defeats Wizardheimer by jumping on his head, sending him tumbling down the stairs straight into the bowels of his basement.

Trivia
