So I'm in the section of the ice zone right before the boss fight. I'm in a hallway that's blocked by one of those orange-black growths, the kind that can only be destroyed by superheating them with a laser. There are tons of those shielded, laser shooting enemies flying around, along with a bunch of ice crystals floating in the water. The natural conclusion would be to lure the shielded enemies into destroying the blockage with their lasers, but that isn't working. Something with their AI just never wants to shoot at me when I get near that thing. Is there something else that I should be doing here?
