Right after talking to U mos for the first time going some where after you might encounter a spinter battle.
In that battle you will see a dark portal opening up. Right be fore the portal infects them you blast them to obviliion(if that even how you spell it).and the portal will be there they do nothing but there just there if you blast them they will explode into little bubles!
