Template:SMRPG Moves Gunk Ball is a special move used by several monsters in Super Mario RPG: Legend of the Seven Stars. Gunk Ball is a very slow-moving magical attack that prevents Mario and his friends from using Special Moves. Gunk Ball is a relatively common special attack that can be used by most of the boss characters and almost all ghost characters. The effects of this attack can be reversed with an Able Juice or Peach's healing special moves.
