This unusually
big rat was encountered by Sir Graham after
he had fallen through a hole in the ground on an island where he was brought
by a friendly condor. He served as some sort of guardian of a door behind
him. The door, it turned out, led to a kingdom of Leprechauns. Getting
past the rat wasn't that hard though. Just as the Bridge
Troll, this guy wanted a treasure. Fortunately, Sir Graham had found
a piece of cheese in the house of Dahlia, the
witch who had stolen the Chest of Gold from King Edward years ago. This
piece of cheese proved to be a treasure good enough for the rat, who swiped
it from Sir Graham's fingers the instant he showed it, and then it disappeared
into a crack in the wall.
