Hmmmm.
Things would be so much simpler if we could see the damn thing.
I had planned to cut a segment of twine, tie it to our kunai, and throw it into the ground, see if that gives us a view of where Crawly is, then we can judge how to handle him. If it charges the kunai, we can either pull it back up, or simply let the string go. Either way, we can then stab Crawly the head with our pitchfork, or throw another kunai at it. If it doesn't charge, we pull the kunai back up, no harm done, and then go from there. I'd rather not jump down when we don't know where it is, but if we have to, so be it.
