The Clockwork Smurf blueprint will was ashore on the island in a message in a bottle. Once the blueprint has been found, a new sign will come available under the status bar. Clicking that will give information on the progress of his creation.
To complete Clockwork Smurf Handy needs 10 pieces. It is possible to buy the pieces with Smurfberries, but as each piece costs 25 Smurfberries, it costs 250 Smurfberries to complete him using only Smurfberries.
This is most likely done to prevent people from finishing him early and hence making them enjoy the quest of completing clockwork longer.
There are two ways to get a piece for Clockwork Smurf. There are special message in a bottle quests that will give a piece as a reward.
The other way is to get bolts as a gift from your neighbours (If you want to add neighbours go to Add Me page). For the first ten bolts one receives, one piece for Clockwork Smurf will be completed. After that the number of bolts needed will increase by ten for each piece, i.e. it takes twenty bolts for the third piece, thirty bolts for the fourth piece etc. That means it takes up to 460 bolts to complete Clockworks Smurf. Please note, if your neighbours don’t have a Clockwork Smurf blue print you cant give them bolts.
To give your neighbour a bolt, you have to visit their island, and then open the gift menu and the last gift on the list will be the bolt. If your neighbour has not yet found the Clockwork Smurf Blueprint, it will not be possible to give them a bolt.
Once Handy Smurf has finished building Clockwork Smurf, he will walk around the island and give quests on his own. Clockwork Smurf does not have his own mushroom house.
