Nuranuru

The Nuranuru are gastropod creatures found in swamp environs, primarily the Misery Mire in A Link to the Past. These slugs have adapted the strange ability to lay bomb-like explosives that can damage nearby intruders and prey. Their bomb-laying method is similar to the Puff Bomber, quick and unsuspecting, with no knowledge whatsoever of how explosives can be contained in a biological creature. They are however, vulnerable to their own bombs, and so can be killed by the very weapon they create.

Trivia

 * Nuranuru's name is based on Nuranura (ぬらぬら), the Japanese for "Slimy".
 * An early beta version of Twilight Princess included what appears to have been a Nuranuru or a Sluggula, however this enemy was never included in the final version of the game. It may have been replaced by the Torch Slug.
