Kelly's magic gold key has been stolen and, along with it, her memory of the magical doors.
The thief is well-known dog burglar, Smiffy Jones: a white fluffy dog who steals unattended trousers in the middle of the night. Toby and Kelly must get the key back before it falls into the wrong hands and puts the magical doors at risk.
They hunt for Smiffy across rope bridges over bubbling mud, look for clues in time-bending ponds, and try to avoid being captured by silly giants.
Will they find Kelly's key before it's too late?
