The first player (mustache and glasses) has the Rowboat Ticket. You have to get a photo from the boat and return it to Mews. When you come back to Loch Ness, you play against one of the other two for a Submarine ticket. You bring that photo back to the Pub, where you find it isn't real, but get to play the first player again.
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).
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).
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.
You only play darts at the Pub to win tickets to the rowboat and submarine rides. The third time you play is against the first player you played. On your first trip to Loch Ness, you get the digital camera and play darts to get a rowboat ticket. You get a photo and take it back to the Mews lab. On your return to Loch Ness, you play darts against a second player to earn a Submarine ride, and photograph the "Nessie" at the bottom of the Loch. Return to the Pub to find it is a movie prop, but beat the first player again and you get a Pennywhistle from the bartender.
You don't find the tickets, you "earn" them playing darts at the Pub. Go right at Loch Ness to find it.
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.
