 Mario & Luigi: Partners in Time
Baby Mario and his brother Baby Luigi, star alongside Mario and Luigi in Mario & Luigi: Partners in Time. Baby Mario and Baby Luigi first meet their adult selves in Hollijolli Village after the adult Mario brothers have been defeated by Shroobs. They then team up in order to defend Mushroom Kingdom from the Shroobs. Baby Mario spends much of the adventure riding Mario piggyback. He and Baby Luigi eventually acquire hammers in the Vim Factory. After traveling throughout the past, defeating enemies, and eventually rescuing Princess Peach, Baby Mario and company stop the Shroob invasion. Baby Mario, alongside any other character who has originated from the past, return back to their original time period. Prior to returning to the past, Baby Mario gives Mario his hammer as a good-bye gift.
In battle, Baby Mario battles identically to his brother, Baby Luigi. His default attack is jumping on foes, and, until Baby Mario acquires the hammer, can use a hammer to attack spiked foes. The player can time Baby Mario's attacks in order for him to do more damage. When Baby Mario is riding on Mario's back, he can engage in battle when the player presses the appropriate command button at the appropriate time. In piggyback mode, Mario takes all the damage for Baby Mario; when Mario faints, Baby Mario takes his place. If Baby Mario faints in battle, either Luigi or Baby Luigi holds him to avoid enemy attacks. If Baby Luigi faints, Baby Mario carries him; this hinders Baby Mario's dodging capabilities. Baby Mario has more attack and speed than Baby Luigi, but less HP and defense. Compared to his older self, Baby Mario has more speed, but lacks in all other traits.
Baby Mario acquires several overworld traits as he ventures through the game. When Baby Mario and Baby Luigi acquire hammers, they also learn to use the Baby Drill, which lets them dig underground underneath obstacles; it can also be used to get Beans. Mario and Luigi can Spin Jump into Baby Mario and Baby Luigi, causing the Baby Spin, which allows Baby Mario and Baby Luigi to access areas that previous cannot be accessed with the Spin Jump. Mario and Luigi can also roll a Bros. Ball into Baby Mario and Baby Luigi, turning them into Baby Cakes. This enables them to slip through wafer-thin areas that cannot be accessed using the Baby Drill.

 General Information
Baby Mario is described as being mostly brave and courageous, such as when he constantly rescues Baby Luigi. His Super Smash Bros. Brawl trophy information, however describes him as a crybaby. Unlike his older self, Baby Mario is not a silent protagonist and is actually very talkative. He is also very energetic, as seen as when he wins a race in Mario Kart Wii. Baby Mario is also very playful when he joins his adult counterparts and his baby companions in kart and bike races, tennis games, and baseball games. Baby Mario is also shown to be very speedy due to the fact that he is a Speed or Lightweight character in every single Mario series spin-off to date. Baby Mario has a very high Speed stat in Mario & Luigi: Partners in Time. Mario & Luigi: Partners in Time also shows that he is rather impulsive, and Baby Mario's brash use of his hammer has gotten him and the others in trouble multiple times throughout the game.
 Physical Description
Baby Mario has beady black eyes and his large trademark nose. Baby Mario has a layer of brown hair always covered by his trademark 'M' hat. Like most of the babies, his outfit eventually changed. In earlier appearances, Baby Mario wears nothing but a white diaper and his hat. He wears a yellow cape whenever he acquires a Super Star. Later on, he is given a new outfit in Mario Golf, which he continues to wear in his spin-off appearances, sometimes with minor adjustments. In this design he wears a red shirt covered by blue overalls akin to his older self Mario. Originally, the shirt is short-sleeved during the Nintendo 64 era, but his shirt is currently long sleeved as his adult self as of Mario Kart: Double Dash. He also wears a pair of light blue and white sneakers. His emblem was originally a lowercase M in Mario Tennis, but Mario Superstar Baseball and subsequent games changed his emblem to a capital M as his adult self.
