Fiona Penbrooke
Professor Fiona Penbrooke is the author of the book Legends Of Loch, a scientist and someone that believes that the Loch Ness monster exists, so she travels to Scotland to find it! When she can't find it, she makes two big Loch-Ness alike costumes (one submarine and one for ground) to make everyone believe what she believes. The Haggart brothers help her because all they want to do is a big prank, since that's their "hobby". At the end, she teams up with the man she hated the most, Sir Ian Locksley and Dan Chillman to go on a hunt for the real monster after the first real clues!
