Part of the issue is that some of the whites fell on the walkway. I was also confused as to why I didn't just let the whites handle it until I looked closer.
@@shr1mpys It's just far enough to where I'm not so sure. After charging the Pikmin, the stragglers are out of range for sure. It's just a situation that's easy to look back on in retrospect while at the time it wasn't even clear if the others would make it in time.
Make sure you have Oatchi fully upgraded since his huge carrying capacity helps a ton with collecting some of the heavier treasures. Make sure you use Go Here a lot to save time walking to places as well
