bow
i'm scared about finger, but I don't have a better guess yet. Let's talk for a second. My problem with a "jester/gesture" pun is that one also gestures with ones hands. (For that matter, a gesture is a way to POINT...) Like, if our last clue was finger, Ipofanes would've needed to've found some clue that clued FINGER but specifically didn't clue HAND (which was not just a non-word but actively bad for us to guess). And neither Jester nor Mammal can unambiguously be said to single out FINGER and not HAND. I would think that if Ipofanes had been trying to clue FINGER with either of those, he would have been more careful about hand. which in turn makes me think finger isn't one of the answers. But the flip-side is I don't have a better guess.
I agree with you that BOW could relate to a mammal, so there might not be a 3rd "mammal" to find. A jester could also take a bow, if necessary. But that still leaves us one jester clue we straight-up haven't found. in conclusion:
FINGER COMPOUND STRING POINT ROULETTE PICK BRAZIL LOCK TRIANGLE BOOM
of these, one has to relate to jester, and one might relate to mammal. none should relate to weapons, which weakly takes out "boom" for me. i'm really not seeing anything...
feel free to vote for your best guess at this point, I'm clueless and won't blame you if it's wrong! There's no need to drag this out if neither of us knows what's going on.
