Phlegma: "Hi [Your Viking's Name]! I have a big problem. I am constantly watering plats and I have to lug pails back and forth. Is there something you can do to make my work easier? Maybe Hiccup has a good idea."
1- Talk to Hiccup by Flight Club
2- Collect 20 wood logs
Phlegma: "Great. This must be the base of the machine!"
3- Collect 3 leather pieces from Phlegma
Phlegma: "Here, I hope you find it useful!"
4- Collect wheel from Bucket
Bucket: "I don't remember why I have a grooved wheel! You can take it. Mulch said you ca use it to help guide the water to the greenhouse."
Hiccup: "Now that we have all the parts, we'll need Gobber's help to put it all together! He is standing in front of the greenhouse at the Lookout."
5- Deliver parts to Gobber
Gobber: "All right lad/lassie, we created a simple pulley system to solve our problem. See? We don't need anything complicated around here. Leave it to me!"
