Wanderin Goom are basic enemies which first appear in Wario Land: Super Mario Land 3. They are members of the Brown Sugar Pirates, but have no ability to attack Wario. Given that a Wanderin' Goom is defenseless, Wario can defeat it from using any type of attack.
Wanderin' Gooms have a variant named Pirate Gooms, which are dressed in pirate gear and wield a weapon. Although Wanderin' Gooms do not appear in Wario Land II, Pirate Gooms do.
In Game & Watch Gallery 2, the Modern version of Ball features a Wanderin' Goom as one of the objects that Wario has to juggle.
