Sprout has just 3 achievements that can be earned in a single playthrough, 2 are earned through natural progression as part of your playthrough and one is missable.

Achievement #1 = "Sprouted!" is earned at the start of the game when you are on the small island and you select coconut for your seed to grown into. See video walkthrough at the 0m36s marker for further information.

Achievement #2 = "The Octopoop" is earned by having an animal (bird or sheep) eat you and poop you out 8 times, this achievement is missable although there are 3 or 4 opportunities to earn this achievement. See video walkthrough at the 1m32s marker for further information.

Achievement #3 = "Mighty Oak" is earned when you complete the game.
