After unlocking the puzzle box found the secret tunnel to dam and empty Loch Ness.
The work finished, they noted a very tall and bright object standing on the bottom.
Woodbert and Whiskton found next to the tall object, a small amulet and proceeded to fight over the wonderful jewel.

Neither of them made note of the near barren surroundings, nor how the odd shaped object which defied gravity, could stand on a sharp point and never sink in the loch's muddy bottom. For that matter, they didn't notice the only mound close by was watching them.

Is it any wonder they also failed to read the translation of the amulet which read: 'Kaboom'
