How to break purple things on the walls

[ksurl]

I've seen a few around already after you get the 2nd hollow. how do you break these? do you need a different power later? what are they for? these are not the purple things that drop down and let the bugs eat it to blow up the destructable purple walls. just a single round purple thing growing out of the wall

You need the force power ability and a throwing weapon.
