How to Get Fat Yoshi
Super Mario RPG contains a secret yoshi at the Yo'ster Island, who has become something of a legend for his size, but you might not know where and when to find him. The "Fat Yoshi" can only appear if you know where to look and exactly what to do.
When Does the Baby Yoshi Appear?
You can first get to Yo'ster Isle after completing the Forest Maze and getting the second Star Piece, afterwards you'll unlock the Pipe Vault area that provides an exclusive passage to the yoshi sanctuary known as Yo'ster Isle.
Here, you can team up with the classic Green Yoshi to do a minigame rhythm race against Boshi. If you're successful, you'll unlock subsequent racing for all the Yoshis, and can bet Yoshi Cookies to earn even more. While the Yoshi Cookies can be used in battle, they also serve another purpose.
Return back to Yo'ster Isle after you have completed the Marrymore section and defeated Bundt and Raspberry, and you'll find a Baby Yoshi sitting among a pile of eggs.
How to Get Fat Yoshi
The Baby Yoshi that appears in Yo'ster Isle after Marrymore will ask for a LOT of Yoshi Cookies. If you feed him a minimum of 30 Yoshi Cookies over time, you can come back to find the mythical Fat Yoshi.
Getting this many Yoshi Cookies can be tough if you aren't that good at the rhythm game, so we recommend saving at the Save Point nearby before making a big bet, and playing it safe by just watching Yoshi -- though it may take longer with worse odds.
Once Fat Yoshi has been manifested, he can give you random reward items when you give him specific amounts of Yoshi Cookies - in bunches of either 10 or 20 at a time.
When given a correct amount of Yoshi Cookies, he can give you certain items, including Bracers, Energizers, Yoshi Candies, Red Essences, and the Yoshi-Aide, which acts as both a Brazer and Energizer rolled into one!
