"Whaaa!? This garlic looks...funky. Bah! I'll eat it anyway!"

- Wario

The mandrake (originally localized as Nasty Garlic) is an uprooted and brown root with a sour face and a peculiar body shape that first appears in WarioWare: Touched! It is based on the poisonous that, according to legend, shrieks when dug up and kills anyone that hears it.

WarioWare: Touched!
The Nasty Garlic first appears in WarioWare: Touched! in Wario-Man's story. When Wario feels sick, he goes to the fridge and tries to get some garlic to cure his sickness. Though he accidentally grabs the Nasty Garlic, he eats it anyway. The Nasty Garlic causes Wario's immune system to attack the Awful Viruses (where the player can tap the Awful Viruses and get the Wario Viruses to eat them), which then causes Wario to turn into Wario-Man. Once Wario-Man's story is completed, the player can drag the Nasty Garlic to Wario and turn him into Wario-Man in the main menu to play his microgames. Wario can return back to normal by being fed a bomb. If the player drags the Nasty Garlic to anyone else, they get confused instead.

A similar-looking, root-like object appears in the opening cutscene of Ashley & Red's stage, as one of the four ingredients that has to be dragged into Ashley's pot. Like the Nasty Garlic, this object has roots shaped like a body and an annoyed expression with puckered lips on its bulb, but the bulb is yellow instead of brown.

WarioWare Gold
In WarioWare Gold, the incident from WarioWare: Touched! is referenced when Ashley brings similar supposed garlic to the Potluck Gang. Red worriedly identifies it as mandrake root and warns that its cry can be fatal, prompting Spitz to cry like a mandrake as a prank, terrifying Red. If the player fails a microgame in this stage, the following card shows a mandrake. In addition, it is a subject of the souvenir minigames Pumpkin Panic and Root Awakening.

WarioWare: Get It Together!
In Ashley's story in WarioWare: Get It Together!, several mandrakes invade her mansion while she waits for dinner. When they attack her, she turns them into food. The majority of them are turned into donuts. Mandrakes appear in the microgames The Vampire Arose and Veggie Out! A mandrake root appears as a Prezzy and in one of Pyoro's character gallery images.

 * Feed this rotten little treat to Wario!

WarioWare Gold character cards

 * Rank C – The mandrake is a plant from the demon world. When uprooted, it will cry like there's no tomorrow! Or not.
 * Rank B – The mandrake is a critical ingredient in magic potions. And the scent of fried mandrake? Ashley loves it.
 * Rank A – If the mandrake grows to its full and terrifying potential... it bears fruit that's simply perfect for jam!

 * It's a plant...right? Wait, it's staring at me. That's super not normal for a plant.

Trivia

 * In the English version of Super Smash Bros. for Wii U, Palutena's Guidance states that the garlic Wario consumes to transform into Wario-Man for his Final Smash is Nasty Garlic, despite it looking like a normal head of garlic; however, in the Japanese version, Palutena instead makes a note that the garlic is not the mandrake. This has been partially corrected in Super Smash Bros. Ultimate, where Palutena's dialog was edited to replace the incorrect usage of Nasty Garlic with garlic.
