the cannibals of kupaqi quest

does anyone know how to get to the cannibal thats hidden in the walls because i cannot find it and so i cant beat that quest without it defeated

If you removed all the walls you can remove, you are left with one. Go back in the Tunnels and tap a crack. You'll get a message that a wall has been removed and le voila!

ok thx for the help

I have hit every single wall,all the cracks and still nothing.

In the northeastish of the Tunnels, hit a very dark wall, and then another, and another and a few more.

To remove the wall that hides the Cannibal, tap, not hit, the crack on a dark wall in the lower southeast. It's a very faint crack on a dark wall as you face south in the southeast. Tap, not hit.
