How do you get the spiderball for Metroid prime 2 echoes?

Answer 1

First of all, you need to go to the sanctuary fortress, then you should get a message for the spider ball, but you go to the other side of the dynamo works (there is two sides) and then you see this black ball going up and down on the walls, you scan it, you would think it would be a "Dark Pillbug" but you scan it and it says "Spider Guardian" You go in a 'epic' fight, i died three times before i got it, but once its over with, the spider ball is your reward!

Answer 2

You get it from the Spiderball Guardian in the room next to Dynamo Chamber

if you don't know where that is then it is in Temple Grounds.

Answer 3

go to the ice place in the quarintine zone and kill the rock monster
