Use the Submarine Ticket to get the Loch Ness Monster Photo that will be an evidence in the existence of Cryptids in Loch Ness. You found out that the Loch Ness Monster Photo on the boat was fake, and you will need another way to get a photo of the Loch Ness Monster. The people in the pub will help you get Submarine Ticket.
How to Get the Submarine Ticket
You will learn that the photo you taken earlier was fraud, so you confront the man in the rowboat about it. He will leave you the boat. You will use this on your next mission. Now go back to the pub and talk to the two guys on the left. They will tell you that you will find the Loch Ness underwater, you will need Submarine Ticket to get to it. They will give you Submarine Ticket if you can beat him in darts, this time you will use the Peregrin-Feathered Darts. Once you beat him, he’ll give you a Submarine Ticket and Osprey-feathered Darts.
