Ogre-Faced Spider Location
Transition to the Ogre-Faced spider’s zone is in the same zone as the transition to the Robot Spider’s zone.
Transition to the Ogre-Faced spider’s zone is at the bottom left of the screen in the water segment.
Blow up the fake wall underwater with your lasers and you’ll be able to go down into the Ogre-Faced spider’s den. Talk to the Ogre-Faced spider 5 times and he’ll give you his sticker
There are other ways to access this zone but this is the most intentional way.
