おまけビューン Bonus Byūn
The Groucho is an enemy in Mother, found in Magicant and its underground area. It will only perform one action, other than attack. It will simply say "Hello" and walk away from battle, raising the experience points of a single character in Ninten's party. If defeated, it will award experience to the entire party, though the experience received is a much smaller amount. Its English name is based on Groucho glasses.
Groucho, Watcher, Dadseyes, Momseyes, and Foureyes are clearly related in some way based on their nearly identical appearance, shared location, and very similar Japanese names. However, this relation is never explicitly revealed. The existence of seemingly disembodied face acting on its own is never revealed either. All of these enemies are only seen in the bizarre land of Magicant.
