Mario & Luigi: Dinomite Adventure is the second Mario & Luigi game for the Display, after Mario & Luigi: Chicken Out. It is developed by Ninkancho Co., Ltd. and marks a return to the classic gameplay of said series.
Mario, Luigi and Peach are at Dinosaur Land for another vacation, when the former spots some Goombas and Galoombas marching about. Realizing the enemies' affiliation with Bowser, Mario asks Luigi to guard the princess, then goes into battle with the baddies. After the battle, it is revealed that Luigi started paying attention to his brother's fighting instead, and that Peach is missing. The Mario Bros. set out once more to find her.
Toad then runs up to the three, informing them that Bowser has indeed kidnapped Princess Peach. He gives the Bros. their hammers and optionally explains how they are used. As Toad is about to leave, Yoshi licks him up and holds him in his mouth. Mario and Luigi frantically get the dinosaur to spit him out. After he recovers from the panic caused by almost being eaten alive, Toad admits that Yoshi's tongue could allow for some useful tactics in battle. The fungus also figures that the lick move can be used on the same set of overworld actions as the Bros.' hammers.
