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. This form is first used in Dreamy Dozing Sands. While in this form, the Bros. will plow through most enemies and are able to perform the following techniques:

Jump
Pressing makes the stack jump. Mario and the Luiginary Stack can use this to reach platforms or activate switches too high to reach.

Lean Over
While the stack is on a ledge, the player can use to make the stack lean over. The Luiginoids can activate switches this way. If there's nothing to lean against, however, the stack loses its balance and collapses.

Ground Pound
While the Luiginary Stack is midair, can be used to ground pound. The Luiginoids will break through most blocks with a ground pound.

Crouch
Pressing makes Mario flatten the Luiginary Stack. While the stack is flattened, Mario and the Luiginoids will be able to move through low ceilings. Pressing reverts the stack to normal.

Spring Jump
While the stack is crouching, pressing causes the stack to spring, allowing the stack to jump many times higher and crush blocks above it.

Hookshot
Pressing aims the ball at the Hookshot point and pressing  again launches Dreamy Luigi to the nearby point.

This move is a reference to the Hookshot, and the move works almost same as the aforementioned item.

Revert
To revert to normal, the player can press to pile the Luiginoids and then press  to make them jump back into the Luiginoid Generator. Pressing cycles through the various forms the Luiginoids create if there is access to more than one, in this order: Stack → Typhoon → Ball → Pile. Pressing while in the Luiginoid Pile is in formation will cause the Luiginary Work to cease.
