Luiginoid

A Luiginoid is a species appearing in the Dream World in the game Mario & Luigi: Dream Team.

In-game
Luiginoids can be activated with Dreamy Luigi when the player is near a Luiginoid Generator. They can be transformed into three forms: the Luiginary Stack, which can activate the moves Spring Jump, Lean Over, Ground Pound, Jump and Crouch, the Luiginary Ball, which can activate the moves Ball Hammer and Hookshot, and the Luiginary Typhoon, which can activate the moves Spin Jump, Hover Spin, and Tornado. Each form is learned at various intervals in the game. They are also present when doing Luiginary Attacks, where they are the main attacking force. Also, it seems that when Dreamy Luigi is in a crisis, many Luiginoids "fuse" with Dreamy Luigi in order to make him giant.
