Time on Frog Island

This is one of the six Shrub-seeing Achievements related to bringing the plant to certain locations on the island. There are 5 for certain locations and a 6th for having brought your plant to all 5 locations in a single playthrough. We're going to cover both of the Northwest Island Shrub-seeing locations with this Guide.

This specific achievement cannot be done immediately upon starting the game, and because of that, I recommend waiting and doing all of the plant locations at the same time, after you've opened the Northwest Island.

To open the Northwest Island, you need to get the Carpenter/Lumberjack Frog to build a bridge to it. To do that, you need to finish his two quests, first. These Quests can't be done until Day 2, and then its going to take 5 or 6 days for the bridge to be built(I think it depends on weather, but I'm not certain). On Day 2 or later, go to the West of the Village. In the forest to the West/SouthWest of the Blacksmith's house is a clearing with a single stump in the middle. The Lumberjack left his saw here, so pick it up and return it to him. I've always found him in the area near his house(which is East of the Village, across the two bridges), but I don't know if he wanders farther than that.

Once you give him the saw, he'll thank you and chat again to find out he needs his hammer, too. If you found him near his house, head straight South, following the beach South and/or East(DON'T CROSS TO THE EAST ISLAND) until you reach a Bench near a fire pit. Near the small pier here is a hammer. Pick it up and return it to the Carpenter, who is likely in the woods East of his house now. Return it to him, then talk to him AGAIN. This will trigger him getting the wood necessary to build the bridge. From this point on, you just wait however many days it takes for him to build the bridge.

The bridge is North/Northwest of the stump where we initially found the Carpenter's Saw. Once done, grab your plant and cross the bridge. Immediately head straight North. You'll see some ruins on the ground with a circular cliff-face to the Northeast and a large body of water on your left. Go up to the land on the cliff-face to the ruins here to unlock the Shrub seeing ruins achievement.

From here, head Northeast and up the hill here, following it North to a cliff and then West to where the Dodo nests are to also unlock the Silly Birbs Shrub-seeing achievement.
