You get it from the bartender at the Pub in Loch Ness.
On your first visit to Loch Ness, you win a rowboat ticket at darts, but only get a photo of some old tires from the rowboat.
On your second visit to Loch Ness, you get the submarine ticket from the other dart players, but your underwater photo of the bottom of the Loch is only a movie prop. Go back to the pub to beat the first dart player again (a poor sport) and the bartender will give you the pennywhistle.
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 get the Pennywhistle after your third victory in the darts game at the Pub. Take the rowboat out again (the operator has taken off) and go left twice, to a secluded lagoon on the loch. Use the pennywhistle there to summon Nessie.

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.

The pennywhistle is said to summon the creature. After you have made the trips in the rowboat and submarine, you get the pennywhistle from the bartender (the dart player is a poor loser). Go out in the rowboat alone, go left twice to the lagoon, and use the pennywhistle.
Nothing, apparently. However, he gives you the pennywhistle when the darts player is a sore loser.
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.
You pick a spot on the dart board and pull back, still holding the dart and relese
Take the pennywhistle from the bartender and go back to the rowboat. If you haven't done so already, tell off the operator and he will leave. Take the boat out alone and go left TWICE, to a lagoon where you can use the whistle.
You get the pennywhistle after winning your third game of darts at the pub. The first time, you get a rowboat ticket and take the "humps" photo back to Mews. The second time, you win a submarine ticket and get a photo that turns out to be a movie prop. When you beat the original darts player again, he is a poor loser but the bartender gives you the pennywhistle.
