Never Alone (Kisima Ingitchuna)

Cultural Insights:
1. Unlocked on start of DLC
2. When chasing the mouse, you will need to move a spirit to push the boat under an ice platform you can't row under, move the spirit again so it no longer pushes the boat when you row back towards the ice, jump up to the owl.
3. (Still whilst chasing the mouse) After Nuna is given the first orb to throw and you have to return to your boat, there is an owl on an elevated platform just before a spirit with an orb, as the fox, wait for the tall platform beside it to lurch upwards, jump across and run up the wall (tap A repeatedly).
4. In the destroyed village there is an area with 3 spirits carrying orbs, row to the platform beneath the lowest spirit, use the fox to jump onto that platform and then the one to the right, jump and wall run, then jump to the wall behind you and run again, jump onto the rightmost platform, the owl is perched on top.
5. Given for completing the game.

Now watch all of the Cultural Insights (or start to then back out) and the achievement should pop.

You only have to find three owls as you play through the game, the other two are given automatically at the beginning and end.
