The next day, the games begin on schedule, but Locksley calls everyone to his ship to look at new pictures of the monster that his minisub's sunken, yet still working, camera had taken, at a depth well below what a ramshackle homemade submarine like Pembrooke's could survive. These, plus three other photos that Pembrooke had taken several days earlier are enough to convince him that the Loch Ness Monster might be real. The film ends with the gang leaving Blake Castle, during which Velma admits that she's actually glad they didn't see the real Loch Ness Monster, explaining that "Maybe some mysteries are best left unsolved." The final scene shows Scooby briefly seeing what appears to be the real Loch Ness Monster swimming by them in the water.
