Yoshi Limit (わくわく!ヨッシーリミット Wakuwaku! Yosshī Rimitto) is a fanmade game starring Yoshi as the main character. I'm sad that this is not real because it sounds like a good idea, I think: Basically players will have lots of Yoshis to complete a puzzle in a level (it has 5 levels), and there are enemies Yoshis can defeat. Yoshis also have 3 hearts of health in this game and players can increase it by getting hearts (as items) in the world and is damaged by spikes and enemies. If a Yoshi dies, they'll despawn.
