After Lonesome Manor, if the Pipe Organ was not fixed then you have to talk to Gilbert. You can find him fishing near Louis's shack. He asks you to knock Louis's boat out from underneath the dock nearby. All you have to do is use an Anvil Sketch on the dock. The dock will break and Gilbert will give you a power spark.
- If you ride the boat with Gilbert he will bring you out to a green E-Ticket (worth 30 E-Tickets)
