Within the game's data are sprites for the Ice Flower, Yoo Who Cannon, and Jump Helmet attacks from Mario & Luigi: Partners in Time and Mario & Luigi: Bowsers Inside Story, indicating that these moves were planned to make a return.

Of these three, the Jump Helmet is the most complete, with the sprites being reworked to use the 3D perspective mechanic introduced in Dream Team. The Ice Flower's assets consist almost entirely of copies of preexisting sprites, with the flower itself being the only unique graphic, and while the Yoo Who Cannon features bespoke visuals for Mario & Luigi, the cannons themselves are mostly identical to their Bowser's Inside Story sprites.
