Collecting All Apples
First apple you can find in first village on a tree behind the shop.
Second apple you can get as reward for hide-and-seek game with a stone in first village.
Find stone in his house inside a cave on the bottom of career left from village.
Find him a few times. He will hide in village except last one, so feel free to kick each stone you see.
For a last one, you need to obtain water hat by defeating the second robot (main quest).
Go to the greenhouse to the right of the painter's house and pour water on the flower that hasn't bloomed.
Now you have an option to reach clouds above the village by climbing the flower stalk.
Climb up. You will see stone on the cloud.
Game is over, take your reward.
Last apple you can get from huge bird.
Find a nest on the cloud above the first village (on the left from stone after game).
Break all eggs to scare birds. Mother-bird will arrive after it. New quest here!
Find two birds in the village. Both of them on a surface level. Talk with them to force them returns to big mama.
