Willy Whistle (also known as Drunk, Borracho and Bonner) are a type of monster that exist in Bubble World. They are humanoid dwarves/elves/trolls that are practitioners of magick, sometimes referred to as wizards or sorcerers, and are almost always seen carrying a magick staff known as a Star Rod, and a potion bottle. The bottles are something which they use as a form of attack by throwing them at their enemies. They are some of the tougher monsters in the Bubble Bobble Universe, and many Willy Whistles have become notable main villains in the story.
