Goal Star

Goal Stars, also known as Gold Stars, Goalpost Stars, Bonus Stars, or simply Stars, are special points found in Super Mario World and its remake, Super Mario World: Super Mario Advance 2. They are earned by touching the moving tape on the goal post. The higher Mario touches it, the more Goal Stars he will get (from 1–30, then 40, then 50 at the top, which also gives him three 1-Ups). These Goal Stars are saved from level to level, and earning 100 of them will let Mario or Luigi go to the Bonus Game, where they can earn 1-Up Mushrooms.

If Mario does not touch the tape, he will get only a coin from the tape.
