Melanie blinked rapidly in the direction of the lake, expecting the visage of a giant, pink tentacle to fade like a mirage. But no, there it was. There was a giant squid in the lake. And it was waving at them. And their professor was waving back and calling it...Barty? The giant squid had a nickname? And it was Barty, of all things? Must be an awfully friendly gargantuan sea creature to have such a benign nickname.

As the tentacle finally -thankfully- sank back into the water, Melanie thought about the professor's question. Wanting to come up with something a little more inventive, Melanie answered, "Perhaps there is a kelpie in the lake, sir. There's one in Loch Ness, so maybe there's one here too?"
