To complete Puzzle #3: Scarecrows you need to bring fertilizer to the green pumpkin. It will take about 2 hours before it is fertilized. Then have a master builder make a scythe at the construction table from a whale bone. Once this is done have a master farmer use the scythe to cut the yellow grass 3 times. Now collect branches from the dead tree beside the Crafting Hut (you will have to do this several times). Use 2 ropes to tie the scarecrow together. Once the pumpkin has been fertilized bring a child to it so they can carve the scarecrows head, once that has been completed get a master builder to place the carved pumpkin head on the scarecrows body.
