A glitch found in Pikmin 1. In The Distant Spring, find the Smoky Progg's egg. Attack it with Blues, but induce only little damage. Wait a few seconds, and it will heal itself. Should it not have emerged by now, attack again. It should shake a bit and open. Try waiting for the Progg to come. In some cases, it will now not appear, at least not on the route it takes all the time. If you go to check if the egg is still present, it should be gone. If you go back to the onions, there is a high chance it will be standing there.
Although these glitchy steps are unlikely to have effect on the following, it they were present in most cases of the next glitch. Here, the counter will count more Pikmin in Olimar's control than there is said to be on the entire map. E.g., it would look something like this on the counter: 007/006/300. Even when all Pikmin are killed or are put back into the onion, the counter will say there is (in this example) 1 Pikmin in Olimar's command.It is still possible to get 100 Pikmin into the field. The counter will simply go to 100/99/300, and will stay at 100 when another Pikmin is brought out. This glitch has also happened in other places in the game, even when there are no enemies around.
