Silky

A Silky is a worm-like creature that first appeared in Wario Land 3 as an enemy, and later in Dr. Mario 64 as a character disturbed by either Dr. Mario or Wario.

In Wario Land 3, a Silky has the ability to give off a special string from its mouth, which turns Wario into Ball o' String Wario. Silkies appear in several levels such as The West Crater and Out of the Woods, although they are common in the levels that they appear in. Said rooms also typically have winding passages with lots of walls, so if Wario becomes Ball o' String Wario, he will potentially get knocked a large distance back. They can be defeated by any type of attack.
