My absolute favorite Universal ride, next to The Incredible Hulk, Doctor Doom's Fearfall, The Amazing Adventures of Spider-Man, Dueling Dragons, and T2 3D: Battle Across Time... I am a huge Hanna-Barbera fan so seeing all the characters in this ride is pretty cool... Dino only made a cameo and I don't think Huck Hound appears in this ride... neither do Space Ghost or Birdman...
Did you know Universal wanted to buy Hanna-Barbera so that's why they put this ride in? They still sometimes pull out the Scooby-Doo walkaround character for events and stuff... Of course, we all know Ted Turner bought HB, and then WB bought Turner... making it the best family in the world (will only be complete if they buy the post-1986 MGM library from Amazon...)
