Doodle God: Evolution

This is the first 'quest' that unlocks in the 'Doodle God' part of this title (not the 'Doodle Farm' part).

The combinations you want are in the following order:

Human + Island = Beach, Cliffs, Forest
Forest + Human = Bushes, Game, Tree
Human + Tree = Leaves, Stick
Cliffs + Human = Cave, Stone
Leaves + Stick = Shelter
Stone + Stone = Spark
Leaves + Spark = Bonfire
Bonfire + Leaves = Smoke
Human + Map = Hidden treasure
Hidden treasure + Human = Compass, Gold, Spyglass
Human + Spyglass = Black sail, White sail
Smoke + White sail = Merchants
Human + Merchants = Salvation

This will give you the achievement.
