Mr. McTout has just given the Royal Navy permission to test a new diving bell in Loch Ness and the Navy expedition's shortest member, Lieutenant McSquirt, is to make the descent into the Loch. Fearing for the Nessies' safety, Angus and Elspeth try to warn their friends with the Thistle Whistles, but end up summoning Hungry-Ness, who mistakes the diving bell for food and puts it in his mouth. Fortunately, McSquirt thinks he's in a cave until he punches Hungry-Ness' uvula and when the Captain claims to have seen the Loch Ness Monster, McSquirt can't confirm the sighting as a result of being too dizzy from being spat out by Hungry-Ness.
