A Middle Ring (initially the "Middle-Ring") is a ring of light in Super Mario World 2: Yoshi's Island , Yoshi's Island: Super Mario Advance 3 and Yoshi's Island DS. It appears partway through most stages and serves as a checkpoint of sorts. If a Yoshi loses a life after passing through one, he can restart at the point of the Middle Ring. Also, passing through a Middle Ring will increase Yoshi's Star Power by ten and turn all on-screen enemies into stars.
Despite their name, Middle Rings are not always placed in the middle of a stage. Some can be found at the very beginning, or not until near the end. A few stages even have multiple Middle Rings and there are always a couple before boss fights.
