Silky

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, Silky has the ability to give off a special string from its mouth which turns Wario into Ball o' String Wario.

Silky appears to be in a good mood most of the time and is the only character completely based on the enemy from the Wario Land series.
