These seeds are widely available and you just have to shoot them to grab the seeds. You can then place them on the mountain walls to climb. But throwing Grapple seeds anywhere will not work. There are certain specific locations where you can grapple.
After getting the seeds to look for the following purple items on the mountain walls. This is the only place where you can throw the grapple seeds.
