Summary You've probably noticed that there are 1-Up Mushrooms in SM64 that spawn when Mario walks to certain spots. These spots (which I call "1-Up checkpoints") are actually objects that Mario collects, and when he collects them all the 1-Up spawns. The amount of checkpoints each 1-Up has varies between 1 and 4. Also, keep in mind that not all 1-Ups spawn in this way, as some start out stationary on the ground, and others spawn from item blocks, Monty Moles, and butterflies. Since the locations of these 1-Up checkpoints are not always obvious (I mean I didn't even know where some were until this video), this video shows the exact number of checkpoints for each 1-Up as well as their locations. That way, you will no longer have any trouble spawning them.
