This achievement is for when you are playing as Zula, if that's her name, I totally forgot.
At the start of the second level when you're trying to cross a bridge. Go to the left and come to an opening with sheep and a guy playing a flute. Grab the stick from next to the guy while he's playing the flute.
Next make your way to the right side of the sheep into the next area where there is a wolf of sorts caught in a trap. Use the stick on him to free him, then use the lantern to heal him. He will run off. You will get the bark and bite achievement for this.
Make your way back to the sheep. The wolf slaughtered everyone including flute guy. Grab his flute. Head back to first area and interact with the owl while having the flute equipped.
