Wanderin' Goom

Wanderin' Gooms are small, oval-shaped creatures that appear in Wario Land: Super Mario Land 3. They have no arms, are not aggressive, and have no ability to attack.

Although considered an enemy in the game's manual, these creatures are extremely weak and are completely harmless. A Wanderin' Goom normally walks in a straight line, but upon coming into contact with any object, it would flip onto its back. Wario can defeat these defenseless creatures any way he sees fit.

There are several other beings identified as Gooms in the Wario Land series including Pirate Gooms, Para-Gooms, and Spearhead.

A single Wanderin' Goom appears in Game & Watch Gallery 2 as one of the objects Wario has to juggle in the Modern version of Ball.

While not identified as Gooms, several other Wario Land games contain similar harmless enemies such as Horned Toady, Marumen and red Bandineros.

Trivia

 * Wanderin' Gooms have unused sprites spitting a projectile, but they do not attack in the final game.
 * The back of Wario Land 3's box states that Wanderin' Gooms appear in the game, but they are nowhere to be found. It is likely that this refers to Spearhead or Para-Goom.
