There's one character I can't seem to find no matter where I look and was hoping someone knew what I have to do. I have the rabbit, fox, shark, lizard/kobold, sheep, robot body for AI, dragon, and snake. Who else is left and how do I get them? Also if someone could explain what the crystals you can break during a drill attempt are for, it'd be appreciated. At this point, I don't really care about spoilers (I tried solving both mysteries myself for for over a month with no luck). I just want to see what I'm missing out on.
