Ah...the answer is Baby Luigi. I would've said something with "green" in one of the hints but that would've gave him away quickly. Here is why Baby Luigi is the answer:

1. Baby Luigi is one of the smallest characters in the series. Note: one of the smallest! Not just the single smallest characters.

2. Baby Luigi often appears in the sports spinoffs such as the Mario Kart series or the Mario Golf/Tennis series.

3. Baby Luigi is one of the main characters of Mario & Luigi: Partners in Time which is an RPG game.

4. Baby Luigi is going to reappear in Mario Kart 8.

5. Baby Luigi is the youngest of the two characters. Since Luigi is younger than Mario, it is obivious that Baby Luigi is younger than Baby Mario.
