Scooby-Doo! And The Loch Ness Monster DVD special feature
Shaggy and Scooby wanted to tell Kid Y if Nessie the Loch Ness Monster was real. Kid Y had a huge house that was about Cryptozoology. Kid Y was unsure whether that Nessie exists or not. He says he doesn't like Scotland much as the ground is damped, and the heather makes him sneeze. And there was apparently nothing to keep him warm in his stupid kilt. He then uses a 3-D T-Rex that roars, frightening Shaggy and Scooby. When Shaggy asked what it was, it was a plesiosaurus (although the image he's showing is actually the head of a Brachiosaurus). He says that witnesses believe that the Loch Ness Monster is really a plesiosaurus. Shaggy says if the monster is more than a 100 years old, it probably lost most of its teeth. Kid Y predicted that there was no lake until after 65 million years ago. After the last ice age, the place formed a loch, which is Scottish for lake. Kid Y also knew a type writer who gave a nickname to the Loch Ness Monster: Nessie. Then, a Latin name was given to the creature: Nessiteras rhombopteryx. Another detail for Nessie is the diamond-shaped fin. Kid Y also explained that the most famous 1934 photo turned out to be fake for 41 years. The "creature" in the image was actually a plastic headed planted on a toy submarine. Shaggy suggested that they could have used a "Loch Ness rubber ducky". Kid Y also revealed that some people have created hoaxes such as Loch Ness Monster "footprints", which turned out to be stuffed hippo feet. This is a little strange since no one reported that the Loch Ness Monster actually had feet. Some mistaken identity could have been Baltic sturgeon (which are rare) or a family of otters.
He also knew that two people from Scotland had created a female Loch Ness Monster to lure the real monster. When they cue the walrus mating call (which is just a weird shout), it apparently attracted a walrus (which are not native to Scotland).
Kid Y also knew other creatures such as a chupacabra, a yeti, sea sirens, Bigfoot, Minotaurs, Gorgons, and the Mongolian death worm that might be out there (though at least three don't really exist in the modern world). The creatures are referred to as the Unexplainables.
When Shaggy asked if the Loch Ness Monster is real, the answer was maybe or maybe not. Kid Y heard his mother calling him for dinner, and he told Scooby and Shaggy that he had to go.
