List of Mario & Luigi: Dream Team pre-release and unused content

This is a list of pre-release and unused content for the game Mario & Luigi: Dream Team.

Early ideas
Early in planning, the developers considered having Bowser be a playable character again, but decided against it to keep the focus on Mario and Luigi. An unused Luigianariy attack involved multiple luigis forming a volcano and spouting out many Luigis was cut because it was deemed "not very good to control"

Early builds
An early prototype featuring a number of Luigis on screen was made during development, and the player had to guide them to a goal without losing any.

Unused data
Some sprites of an earlier design of Dreamy Bowser can still be found within the game.

A number of leftover sprites from Mario & Luigi: Bowser's Inside Story are also present in the game's files. These include sprites for Mario, Luigi, a Goombule, a Shroob, a Blitty. There are also sprites for some of the Special Attacks in Bowser's Inside Story, including Jump Helmet and Yoo Who Cannon. Some sprites for an Ice Flower attack are also present.
