Beat the first player (wearing glasses) and take the rowboat ride, and bring the photo back to Mews. Return to play the other two players to win a submarine ticket (with better darts).
On cryptids island, you have to get to a certain point and do a rematch with a guy at darts. Then he will say you cheated but the bar guy will give you the pennywhistle anyway.
It is at Loch Ness.
There does not seem to be a horn on Cryptids Island. There is a flute (a pennywhistle) which you receive after the submarine ride, after you defeat the sore loser at darts again.
They aren't arrows, they are darts (see the related question).
you battle that guy that you battled before at darts and you deafeat him at darts and then you the barman gives you a pennywhistle then you go to the rowboat and go left 3 times and then you use your pennywhistle and Nessie cmes out.
Nothing, apparently. However, he gives you the pennywhistle when the darts player is a sore loser.
yes there is
The Pub is to the right of the loch at Loch Ness. You will play darts there to win the tickets to the rowboat and submarine.
You win at darts a second time and get a submarine ticket.
On your first visit to Loch Ness, you can win a rowboat ticket by playing darts at the Pub (to the right of the Loch).
You don't find the tickets, you "earn" them playing darts at the Pub. Go right at Loch Ness to find it.
All of the darts players are at the Pub to the right of the Loch in Loch Ness. You can acquire the camera, the matches, and the rowboat ticket on your first visit. After you take a photo of the Nessie "loops" back to Mews, return to the Pub to play against two others for a Submarine ticket. After you have your underwater photo, you will play the first guy again, and eventually get the Pennywhistle.
