In various levels throughout Super Mario World, bonus rooms where groups of three blocks must be hit in the correct order for a 1-Up can be found. There is a way to cheat at this mini-game and always collect every 1-Up by entering the bonus room as Cape Mario carrying a Koopa shell. By placing the shell on the ground and spinning Mario’s cape to make it hit the blocks, every hit registers as correct regardless of the order.
