Snake Charmer is a souvenir located in the Toys folder in WarioWare: Twisted!. It features a cyan toy snake, whose parts and how they are connected are all easily visible, set on top of a plate. When the console is titled, the snake moves towards the plate's center until its entire body is coiled in a spiral. Twisting further causes it to vibrate heavily and change colors. If the tilt is sustained for about two seconds, the snake shatters at each part's connection, and a second snake soon reemerges. Twisting back lets it keep its current color, though this doesn't reset how much time is needed until it breaks.
