Yoshi (species)

When Mario and his current set of partners visit Glitzville in Paper Mario: The Thousand-Year Door, they soon find themselves with custody of a Yoshi egg, after its initial owner, a hotdog vendor, decided against cooking and serving it once he realized it could move on its own accord. For a while, the egg follows Mario and his partners. Then, after the match with the Armored Harriers, Mario returns to find that the egg had hatched into a baby Yoshi, the colour of whom varies depending on how much time had passed between Mario's acquisition of the egg and its hatching. Mario names the Yoshi, who then travels with him and the other partners for the remainder of the game, before becoming a fighter at the Glitz Pit after the quest is over. One of the Yoshi's attacks involves summoning a stampede of green Yoshis to trample the enemy, and another green Yoshi businessman can be found on the Excess Express.
