A quick walkthrough for a quick 100% achievement.
One scarecrow. Only
Go northwest from where you start the game, a scene should play between 2 npcs then kill the four scarecrows in their yard.
Don't interrupt me, please
After the scarecrows, head northeast till you reach a woman with a bunch of chickens. A scene will play and you will need to knock the chickens out (RT) and drag them back into the shed (hold LT).
Head northeast from the chickens and attack the stone guy.
Turnip, potato and corn
Head north from the chickens and imposter and you will find 4 farmers, a scene will play then step over 80-90% of their cabbage.
The ball. Of doom!
From the four farmers, head northwest till you reach the back of the church (stay near the west trees so you dont start the talk with the priest), go up to the blue ball.
Cowards and wine
From the blue ball, go back to the front of the church and talk to the priest. A scene will play and a bunch of red enemies will spawn, kill them.
Sticks and stones
Head northeast from the priest, after a quick nap, continue northeast till you reach a fork in the road going south or east. Head southwest till you get to a stone and hit it with your sword.
Now go back and head down the east path till you reach the boss. Get him to charge into the gate three times, then continue south and you've beaten and 100% the game!
