Snawful

Snawfuls are snowman-like enemies that assist Blizzard Midbus during the events of Mario & Luigi: Bowser's Inside Story. In battle, these enemies will attempt to freeze Mario, Luigi, or Bowser. When killed outside of Bowser, they just melt, but when inside, they will melt, and leave cold air inside Bowser, usable for later. After taking out a Snawful inside Bowser's body, a counter of how many Snawfuls have been defeated will be shown. If the Mario Brothers inside can defeat 5 Snawfuls, Bowser will breathe out enough cold air to make it set an ice ball on top of Midbus's crown, disabling him from making any more Snawfuls.

Trivia

 * Snawful is a pun of "snow" and "Fawful".
