What's the rarest Yoshi?

Could you elaborate on what you mean by "rarest Yoshi"? Are you referring to a specific type of cryptocurrency, a rare collectible item, or perhaps a character from a game or media franchise? Without more context, it's difficult to provide a definitive answer. However, in the realm of cryptocurrency, rarity is often associated with the scarcity and demand for a particular digital asset. If "Yoshi" is a cryptocurrency or token, the rarest version would likely be the one with the lowest supply and the highest demand among collectors or investors. Alternatively, if "Yoshi" refers to a character or item in a game or media franchise, the rarest version would depend on various factors such as availability, rarity within the game's economy, and perhaps even sentimental value for fans of the franchise. Can you provide any additional information or context to help me give a more accurate response?
