Daffy Duck starts Mysterious Phenomena of the Unexplained by stating he has a surprise for the audience: live footage of the Loch Ness Monster. He hands proceedings over to Porky Pig; however, Porky had confused the Loch Ness Monster with the band of the same name, whom he bills as the "noisiest band in the world". A surprised Daffy demands, "are you in Scotland?" Porky confirms he was actually in Detroit, Michigan, where the band was performing live. Daffy decides to go to Scotland to find Nessie himself.
Upon arrival at Loch Ness, and getting hit by an incoming golf ball, Daffy seeks help from local Yosemite Sam, who agrees to help after having him pay a fee. Sam first takes Daffy to a telescope where he has to pay to view Nessie. Sam tricks Daffy into seeing Nessie using an actual fake photo. He takes Daffy onto the loch in a boat from which Daffy explores the loch in a diving suit, though Daffy has to pay extra for air. The diving suit breaks when Sam, after being hit by a golf ball, accidentally increases the air flow into the suit which causes it to inflate like a balloon then deflate, causing Daffy to fly into the screen, cracking the helmet.
Daffy then uses a submarine, which Sam got at a yard sale, to explore the loch; the latter has Daffy give him his credit card beforehand. Just as Daffy sees on his radar that Nessie is approaching him, Sam raises him up because his credit card maxed out. They are both hit by a golf ball which, to their surprise, came from Nessie. Nessie plays golf and goes into the loch to retrieve the golf balls. While Sam is amazed, Daffy isn't, commenting that Nessie's shot was the worst slice he'd ever seen.
- The lead singer of the band was actually from a Lobo Webtoon. The character is called Major Snake. The other members of the band are from the same web series.
- While this webtoon is the third of the webseries, it was released after "The Taming of the Screwball" in 2002.
- Daffy's Acme Express Card number is 505N 47PU.
- The photo Sam uses to trick Daffy into seeing Nessie is based on the actual "surgeon's photograph" from 1934.
- In its original release, after Daffy spots Nessie approaching in the sub, the webtoon would shift to an interactive mini-game in which Daffy could find various items in the depths of the loch.
