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.

Luiginary Typhoon
Pressing turns the Luiginary Stack into the Luiginary Typhoon, which looks like an inverted cone, with Mario on top. This form is first used in Dreamy Mount Pajamaja. While in this form, the Bros. will also plow through most enemies and are able to perform the following techniques:

Spin Jump
Pressing makes the Luiginary Typhoon jump, which falls slower than a normal jump. Pressing while midair makes Luiginary Typhoon drop quickly.

Hover Spin
Pressing while midair makes Mario Jump, making the Luiginary Typhoon rise a bit, increasing the aerial duration a bit. Mario will also be able to hit ? Blocks above him.

Tornado
Pressing creates a large tornado, with all the Luiginoids whirling around. You can control where Mario goes with, and push crates that have been affected by the tornado. Pressing will return Mario and all the Luiginoids to their original location.

Luiginary Ball
Pressing turns the Luiginary Typoon into the Luiginary Ball, which looks like a sphere, with Mario balancing on top. This form is first used in Dream's Deep in Dreamy Pi'illo Castle, later in the game. While in this form, the Bros. will plow through most enemies, move faster than other Luiginary Forms, fly up ramps, and are able to perform the following techniques:

Ball Hammer
Pressing causes Mario to swing the Luiginary Ball around and around, breaking certain obstacles. Mario can move up and down in this state. Pressing again will launch the Luiginary Ball a far distance, returning to Mario almost immediately. Pressing will cause Mario to balance on the Luiginary Ball again.

Hookshot
Pressing aims the ball at the Hookshot point and pressing  again launches Dreamy Luigi and a string of Luiginoids to the nearby point. If the line is not aimed at a Hookshot point, the Luiginoids will spring back.

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. Alternatively, pressing while in the Luiginoid Pile will also cause the Luiginary Work to cease.
