Luiginoid Formation

Luiginoid Generator is a type of Luiginary Work in Mario & Luigi: Dream Team. It has many uses for Mario and Dreamy Luigi.

Luiginary Stack
If the generator contains a Luiginary Stack, then a stack of Luiginoids will form and Mario will climb to the top. While in this form, the Bros. will plow through most enemies and are able to perform the following techniques:

Jump
To jump, simply press. You can use this to simply reach platforms or activate switches too high to reach.

Lean Over
While on a ledge, move to make the stack lean over. The Luiginoids can activate switches this way, but watch out: if there's nothing to lean against, then the stack will fall apart.

Ground Pound
While in midair, press to ground pound. The Luiginoids will break through most blocks with a ground pound.

Crouch
Press to crouch. In this subform, Mario and the Luiginoids will be able to fit through areas you can't normally. Press to return to normal.

Spring Jump
While crouching, press to spring up, allowing the stack to jump many times higher.

Hookshot
Press to aim at the Hookshot point, and press  again to launch Dreamy Luigi to the nearby point.

The name "Hookshot" is likely the reference to the Hookshot, and the move works almost same as the aforementioned item.

Revert
To revert back to normal, press to pile the Luiginoids, then press  to make them jump back into the Luiginoid Generator.
