There was no way to see the actual monster on the Cryptids Island preview. Likewise, there is no way to see Nessie with the telescope in the actual quest. All you see is items disappearing into the water.

Nessie is a nickname for the Loch Ness Monster. =D
In the viewfinder (binocular telescope) at Loch Ness, a little Scottish Terrier is visible and will bark at you when you see him.
The loch ness monster on poptropica in Cryptids island in the viewfinder. When you click the viewfinder, stay near the top of the water where the rocks are. You will find Nessie near a rather flat rock. And near the front, will be two rocks together behind a piece of land.
The Scottish Terrier nicknamed "Sparky" appears in the viewfinder (binocular telescope) at Loch Ness. If you clicked on him during the Preview, he would bark at you. He is not part of the Cryptids island quest.
One dog, a little Scottish Terrier, appears in the viewfinder (binocular telescope) on the hill above Loch Ness. During the preview, he would bark when you clicked on him. But he is not part of the island quest.
You have to look for Bigfoot/Yeti in the Himalayas, the Jersey Devil in New Jersey, the Loch Ness Monster in the Loch Ness in Scotland and the Chupacabra in Puerto Rico.
In the demo for the island, players could look around through the viewfinder overlooking the Loch. Some would see a shadowy shape of Nessie, and win Cryptids costume items. (see related blog link)

During the special preview of Cryptids Island (beginning December 2, 2010), anyone who spotted Nessie got a special Nessie hat. However, you could not always see Nessie, and when you did she was a distant shape on the loch. Players could only view the loch for a brief period each day. (see related link)
You get them in Loch Ness.
